This comprehensive stores accounting system development guide provides a practical, industry-standard, stepwise plan for building robust applications. Whether you’re planning stores accounting system development for cartridge management or broader inventory control, this guide contains architectural guidance, data model recommendations, workflow & transaction patterns, security best practices, test & deployment guidelines, and ITIL process mapping. Learn more about MS SQL Server best practices and ASP.NET WebForms development.

Executive summary (one-line)

Build a secure, auditable n-tier WebForms application backed by MS SQL that implements a request → HOD approval → store-keeper issue/receipt workflow, integrates with your org’s identity source, and follows ITIL Service Request / Asset & Configuration Management practices.

Phase-0 — Preparations (before coding)

Stakeholder & requirements workshop
- Participants: Employees (requestors), HODs, Store Keeper, IT ops, Procurement/Finance.
- Outcomes: functional requirements (fields on request form, approval rules), non-functional (SLA, performance), integration points (AD, HR/Payroll, Finance).
- Define acceptance criteria for MVP (see checklist below).
Define Roles & SLAs (ITIL Service Catalogue)
- Roles: Employee, HOD, StoreKeeper, SystemAdministrator.
- Example SLAs: HOD approval <= X business hours (document this), Issue to employee within Y hours.
- Approval policies (auto-escalation rules if HOD doesn’t respond).
Environment & toolchain setup
- Source control: Git (or TFS). Branching strategy.
- CI: Jenkins/TeamCity/Azure DevOps.
- Issue tracking: Jira/TFS.
- DB change management: migrations/SQL script repo (versioned).
- Test environments: Dev, QA/UAT, Staging, Prod.

Phase-1 — Stores Accounting System Development Architecture & Design

N-tier architecture
- Presentation: ASP.NET WebForms (UI pages, master pages).
- Business Logic Layer (BLL): C# class library implementing workflows, validation, authorization.
- Data Access Layer (DAL): parameterized stored procedures or ADO.NET repository (or EF if preferred).
- Integration Layer: connectors for AD/HR/Finance (Web Services/REST).
- Persistence: MS SQL Server (schemas, backups).
- Monitoring/Logging: ELMAH/log4net + SQL / file logs.
Non-functional
- TLS everywhere (HTTPS).
- Least Privilege for DB accounts.
- Performance: paging for grids, caching static lookups, optimized indexes.
- Scalability: design for multiple web servers behind load balancer.
Deployment
- Application config transforms per environment.
- DB migration process + rollback scripts.
- Runbooks for deployments with approvals (ITIL Change Management).

Phase-2 — Data model (MS SQL) — design & implementation

Design for 3NF where practical; use surrogate integer keys for performance. Use ROWVERSION (timestamp) for optimistic concurrency.

Core entities (logical)

Users (UserId, ADUserName, DisplayName, Email, DepartmentId, RoleId(s))
Departments (DepartmentId, Name, ManagerUserId)
Items (ItemId, SKU, Name, Description, Unit, ReorderLevel, SupplierId, IsActive)
Inventory (InventoryId, ItemId, LocationId, Quantity, RowVersion, LastUpdated)
Requests (RequestId, RequestNumber, RequestedByUserId, DepartmentId, Status, CreatedAt, UpdatedAt, HODUserId, HODDecisionAt, Comments)
RequestItems (RequestItemId, RequestId, ItemId, QuantityRequested, QuantityIssued, QuantityReceived)
IssueRecords (IssueId, RequestId, IssuedByUserId, IssuedAt, Remarks)
ReceiptRecords (ReceiptId, ItemId, Quantity, ReceivedByUserId, ReceivedAt, RelatedDocument)
AuditLog (AuditId, EntityType, EntityId, Action, OldValue, NewValue, ChangedBy, ChangedAt)

Suggested columns & types (example)

Users.UserId INT IDENTITY(1,1) PRIMARY KEY
Items.ItemId INT IDENTITY, SKU NVARCHAR(50) UNIQUE, Name NVARCHAR(200), ReorderLevel INT, IsActive BIT
Inventory.Quantity INT CHECK (Quantity >= 0), RowVersion ROWVERSION

Constraints & indexes

FK constraints for data integrity.
CHECK constraints for numeric ranges.
Indexes:
- Items: (SKU) unique
- Inventory: (ItemId), covering index on (ItemId, Quantity)
- Requests: (RequestedByUserId), (Status), (CreatedAt)
Use filtered indexes for active items.

Data access pattern

Create stored procedures for critical operations (CreateRequest, ApproveRequest, IssueItems, ReceiveItems, AdjustInventory).
Use parameterized queries for everything.

Phase 3 — Workflow & state machine

Define statuses
- e.g. Draft (0), PendingApproval (1), Approved (2), Rejected (3), Issued (4), Received (5), Closed (6).
State transitions
- Employee → Submit → PendingApproval
- HOD → Approve → Approved (or Reject → Rejected)
- On Approved → notify StoreKeeper (creates fulfillment task)
- StoreKeeper → Issue → Issued (decrement inventory)
- Employee → Confirm receipt (or StoreKeeper records Receipt) → Received → Closed
Audit trail
- Every transition writes an AuditLog entry with who/when/why.
Escalations
- Schedule a background job (SQL Agent job or Windows service) to find PendingApproval older than SLA and escalate/notify.

Phase 4 — Concurrency, transactions & inventory integrity

Inventory updates must be atomic and prevent oversell.

Safe pattern (T-SQL pseudo code):

BEGIN TRAN;
-- atomically decrement if enough stock
UPDATE Inventory
SET Quantity = Quantity - @qtyRequested
WHERE ItemId = @itemId AND Quantity >= @qtyRequested;

IF @@ROWCOUNT = 0
BEGIN
    ROLLBACK TRAN;
    -- return error: insufficient stock
END
ELSE
BEGIN
    -- insert IssueRecords, update RequestItems (QuantityIssued), insert AuditLog
    COMMIT TRAN;
END

Alternatives:

Use sp_getapplock to serialize access per ItemId for high contention scenarios.
Use ROWVERSION optimistic concurrency when updates are initiated from application, and handle conflict retries.

Set transaction isolation appropriately; prefer short transactions. Consider READ COMMITTED SNAPSHOT isolation to reduce blocking.

Phase-5 — Stored procedures & DAL guidance

Stored procedures for business-critical work
- usp_CreateRequest, usp_ApproveRequest, usp_RejectRequest, usp_IssueRequestItems, usp_RecordReceipt, usp_AdjustInventory.
Return codes / structured results
- Use output parameters for result codes and messages.
Error handling
- Use TRY/CATCH in T-SQL and return meaningful error codes/messages to BLL.
DAL
- Implement repository pattern + unit of work.
- Use parameterized SqlCommand and using blocks for connection disposal.

Phase-6 — ASP.NET WebForms (presentation layer)

UI pages (minimum MVP)
- Login (AD/Forms)
- Request Create/Edit (Employee)
- My Requests (employee view) — GridView with paging and filters
- Approval Queue (HOD) — bulk approve/reject
- Store Keeper Dashboard — Approved requests to fulfill
- Inventory Management — view/edit stock levels, reorder points
- Audit & Reports — admin
UX best practices
- Use MasterPages for consistent layout.
- Use server side validation + client side (Validators + jQuery).
- Prefer minimal ViewState (disable where not needed).
- Use UpdatePanel sparingly — prefer WebMethods/AJAX for lightweight calls.
Security in WebForms
- Use Windows Auth / AD integration where possible (FormsAuth with AD fallback).
- Map AD groups to application roles.
- Protect pages with <location> or role checks in code behind.
- Anti-CSRF: set Page.ViewStateUserKey = User.Identity.Name and validate.
- Use input sanitization and HttpUtility.HtmlEncode for output to prevent XSS.

Phase-7 — Authentication & Authorization

Authentication
- Enterprise: integrate with Active Directory (Windows Auth or LDAP/Forms + AD).
- Else: use ASP.NET Membership (but store credentials securely).
Authorization
- Role-based access control (RBAC).
- Fine-grained permission checks in BLL (e.g., CanIssue(RequestId, userId)).
Secrets & credentials
- Do not store connection strings with plain text passwords in source control.
- Use secure config transforms and environment secrets stores.

Phase-8 — Auditing, logging & monitoring

Audit requirements
- Record any create/modify/approve/issue/receive actions with user, timestamp, IP, old/new values.
- Store audit records in a write-optimized table (separate schema).
Application logging
- ELMAH for uncaught exceptions; log4net or Serilog for structured logs with correlation IDs.
Monitoring
- Capture metrics: requests per day, average approval time, stockouts, reorder triggers.
- Use alerts for low inventory, failed jobs, or high error rates.
Retention & GDPR
- Define retention policies for logs/audit data.

Phase-9 — Reporting & KPIs

Deliver standard reports:

Current stock by item & location
Reorder alerts
Pending approvals and age
Request fulfillment SLA compliance
Issue/receipt history by user/department

Design reports as stored procedures/views for performance; exportable to Excel.

Phase 10 — Testing strategy

Unit tests for BLL methods (MSTest/NUnit).
Integration tests for DAL (use test DB).
UI tests (Selenium) for core user journeys.
Load testing (JMeter) for peak usage.
Security testing: SQL injection, XSS, CSRF, authentication attempts.
UAT: HODs, StoreKeeper, Employees run acceptance scripts.

Create test cases for each user story and acceptance criteria.

Phase-11 — Deployment, change & release management (ITIL)

Change Management
- All changes go through a Change Request with CAB approval for prod deployments.
Release Plan
- Maintain release notes, DB migration scripts, rollback plan.
Environments
- Separate configs and secrets for Dev/QA/Staging/Prod.
Backups & DR
- Full DB nightly, transaction log backups every X minutes depending on RPO.
- Test restore procedures quarterly.

Phase-12 — Operations & ITIL process mapping

Service Request Fulfillment
- Define request model for cartridges as a Service Request item in Service Catalogue.
- Automate fulfillment workflow as implemented in app.
Configuration Management (CMDB)
- Record application components, DB versions, server details, service accounts.
- Track item SKUs & supplier details as CMDB items if required.
Incident & Problem Management
- Define incident severity, logging process, escalation contacts.
Continual Service Improvement
- KPIs review monthly: request fulfillment time, rejection rate, stockout incidents.

Phase-13 — Security & compliance checklist

HTTPS enforced.
SQL parameterization and least-privilege DB accounts.
Passwords hashed (PBKDF2 / Rfc2898DeriveBytes) if storing locally.
Regular vulnerability scans and pentests.
Audit log immutable / write-only for critical events.
Data retention & privacy compliance (GDPR etc.) — purge old personal data per policy.

Phase-14 — Deliverables & MVP acceptance checklist

MVP must include:

Employee can submit request (one or multiple items).
HOD can view and Approve/Reject (single and bulk).
StoreKeeper sees approved requests and can Issue items.
Inventory is decremented atomically on Issue; Quantity cannot go negative.
StoreKeeper can Record Receipt (incoming stock) to increase inventory.
Audit log of all transitions.
Basic reports: current stock, pending approvals.
Authentication & role-based authorization.
Deployment scripts for DB and app.

Phase 15 — Optional integrations & enhancements (post-MVP)

Auto-reorder integration with Procurement (PO creation).
Chargeback to cost centers (Finance integration).
Mobile friendly UI or mobile app.
Barcode scanning for faster issuance/receipt.

Minimal example: SQL pattern for issuing items (safe transaction)

-- Sample pattern to atomically issue single item
CREATE PROCEDURE dbo.usp_IssueItem
    @RequestItemId INT,
    @IssuedByUserId INT
AS
BEGIN
    SET NOCOUNT ON;
    BEGIN TRAN;
    BEGIN TRY
        DECLARE @ItemId INT, @Qty INT, @RequestId INT;
        SELECT @RequestId = RequestId, @ItemId = ItemId, @Qty = QuantityRequested
        FROM RequestItems WHERE RequestItemId = @RequestItemId;

        UPDATE Inventory
        SET Quantity = Quantity - @Qty, LastUpdated = SYSUTCDATETIME()
        WHERE ItemId = @ItemId AND Quantity >= @Qty;

        IF @@ROWCOUNT = 0
        BEGIN
            RAISERROR('Insufficient stock for ItemId %d', 16, 1, @ItemId);
            ROLLBACK TRAN;
            RETURN;
        END

        -- record issue and update request item
        INSERT INTO IssueRecords (RequestId, RequestItemId, IssuedByUserId, IssuedAt, Quantity)
        VALUES (@RequestId, @RequestItemId, @IssuedByUserId, SYSUTCDATETIME(), @Qty);

        UPDATE RequestItems SET QuantityIssued = @Qty WHERE RequestItemId = @RequestItemId;

        -- audit log entry (simplified)
        INSERT INTO AuditLog (EntityType, EntityId, Action, ChangedBy, ChangedAt)
        VALUES ('RequestItem', @RequestItemId, 'Issued', @IssuedByUserId, SYSUTCDATETIME());

        COMMIT TRAN;
    END TRY
    BEGIN CATCH
        IF XACT_STATE() <> 0 ROLLBACK TRAN;
        DECLARE @ErrMsg NVARCHAR(4000) = ERROR_MESSAGE();
        RAISERROR(@ErrMsg, 16, 1);
    END CATCH
END

(adapt to multi-item requests by looping or issuing per item within same transaction if you prefer atomicity across whole request)

Checklist for going live (operations)

Backup & restore tested.
Load test done with expected peak.
Security scan & fixes applied.
Monitoring/alerts configured.
Runbook available for inventory reconciliation, stockouts, critical failures.
User training completed (Store Keeper, HOD, Employees).

✅ This script sets up:

Core entities: Users, Departments, Roles, Items, Inventory, Requests, RequestItems.
Workflow support: Request approvals, issues, receipts.
Audit trail: Captures all entity changes.
Seed data: Some departments, roles, users, and cartridge SKUs with starting stock.

Would you like me to add the stored procedures (usp_CreateRequest, usp_ApproveRequest, usp_IssueItems, usp_RecordReceipt) right after this so you have both schema + workflows ready to execute?

Perfect 👍 Here are the core stored procedures for your Stores Accounting System (aligned with the schema I gave you).
These cover the full workflow: Create Request → Approve/Reject → Issue Items → Record Receipts.

        VALUES ('Inventory', @ItemId, 'Receipt', CAST(@Quantity AS NVARCHAR(50)), @ReceivedByUserId);

        COMMIT TRAN;
    END TRY
    BEGIN CATCH
        IF @@TRANCOUNT > 0 ROLLBACK TRAN;
        THROW;
    END CATCH
END;
GO

📦 Supporting Type

To make usp_CreateRequest work with multiple items, you need a User-Defined Table Type:

CREATE TYPE dbo.RequestItemTableType AS TABLE
(
    ItemId INT NOT NULL,
    QuantityRequested INT NOT NULL CHECK (QuantityRequested > 0)
);
GO

✅ Usage Examples

-- 1. Employee creates request for 2 cartridges
DECLARE @items dbo.RequestItemTableType;
INSERT INTO @items (ItemId, QuantityRequested)
VALUES (1, 2), (2, 1);

EXEC dbo.usp_CreateRequest 
    @RequestedByUserId=1, 
    @DepartmentId=1, 
    @HODUserId=2,
    @Items=@items;

-- 2. HOD approves request
EXEC dbo.usp_ApproveRequest 
    @RequestId=1, 
    @HODUserId=2, 
    @Decision=1, 
    @Comments='Approved for IT printers';

-- 3. StoreKeeper issues items
EXEC dbo.usp_IssueItems 
    @RequestId=1, 
    @IssuedByUserId=3;

-- 4. StoreKeeper records new stock receipt
EXEC dbo.usp_RecordReceipt 
    @ItemId=1, 
    @Quantity=20, 
    @ReceivedByUserId=3, 
    @RelatedDocument='PO1234';

This gives you a fully working schema + workflows.
Would you like me to now generate sample ASP.NET WebForms (C#) code-behind for the Employee Request Page (with GridView + Add Items + Submit button) so you can test end-to-end?

Great 🚀 Let’s wire this into ASP.NET WebForms (C#).
Below is a sample WebForms page for Employee Request Creation that:

Lets the Employee select items & quantity (via DropDownList + TextBox).
Shows current selections in a GridView.
Submits the request using the usp_CreateRequest stored procedure.

✅ With this page:

Employee picks items + qty → they appear in GridView.
On submit, the system calls usp_CreateRequest and inserts both request + items.
You can then approve/issue/receive using the other stored procs.

Would you like me to also provide the HOD Approval Page (show pending requests in a GridView with Approve/Reject buttons)?

Perfect 👍 Let’s build the HOD Approval Page.
This page will let a Head of Department (HOD) view all pending requests for their department and either approve or reject them. It uses the stored procedure usp_ApproveRequest.

}

✅ How It Works

GridView loads all Status = 1 (PendingApproval) requests.
HOD clicks Approve or Reject.
The gvRequests_RowCommand calls usp_ApproveRequest with the decision.
The grid refreshes with updated data.
Status updates to Approved (2) or Rejected (3), and audit log entry is created.

⚠️ Note: For demo I hard-coded hodUserId = 2. In production:

Use HttpContext.Current.User.Identity.Name to map logged-in AD/Forms user to your Users table.

Do you want me to also generate the StoreKeeper Dashboard Page (to issue items from approved requests and update stock)?

Excellent 👍 Now let’s build the StoreKeeper Dashboard Page.
This page will let the Store Keeper:

See all approved requests (Status = 2).
Open each request to view requested items.
Issue the items by calling usp_IssueItems.

                    lblMessage.Text = $"Request {SelectedRequestId} issued successfully.";
                    lblMessage.ForeColor = System.Drawing.Color.Green;
                }
                catch (SqlException ex)
                {

            // refresh
            LoadApprovedRequests();
            gvRequestItems.DataSource = null;
            gvRequestItems.DataBind();
            btnIssue.Visible = false;
            SelectedRequestId = 0;
        }
    }
}

✅ How It Works

GridView gvRequests shows all approved requests.
StoreKeeper selects one → items load in gvRequestItems.
Click Issue All Items → calls usp_IssueItems.
DB updates: inventory decremented, request marked as Issued (4), issue record logged.
Page refreshes with updated data.

⚠️ In production:

Replace storeKeeperId = 3 with the logged-in user’s ID (mapped from AD/Forms).
Add more UI (filters, search, pagination).

👉 Next step could be a Stock Receipt Page (to record new cartridges received into inventory, calling usp_RecordReceipt).

Do you want me to generate that page as well?

Perfect 👍 Now we’ll build the Stock Receipt Page for the Store Keeper.

This page will allow the Store Keeper to:

Select an Item from inventory.
Enter Quantity Received and an optional Supplier/Remarks.
Submit → calls usp_RecordReceipt stored procedure.
Updates inventory stock and logs receipt.

        }
    }
}

✅ How It Works

Store Keeper picks Item from dropdown.
Enters Qty, Supplier, Remarks.
Clicks Record Receipt.
Calls usp_RecordReceipt, which:
- Increments InventoryStock.QuantityInStock.
- Inserts into Receipts table.
- Logs action into AuditLog.
Shows confirmation message.

⚠️ Production considerations:

Replace storeKeeperId = 3 with logged-in Store Keeper from Users table.
Add validation for large numbers / invalid item selection.
Extend UI to show current stock levels after receipt.

👉 At this point, we’ve covered:

Employee Request Page ✅
HOD Approval Page ✅
Store Keeper Dashboard (Issue) ✅
Stock Receipt Page ✅

Would you like me to also generate a Reporting Page (e.g., Requests History by Department/Item, Inventory Summary)?

Great 🚀 Let’s add a Reporting Page so management (or any role with access) can see Requests History and Inventory Summary.

This page will provide:

Requests Report → Filter by Department & Date Range.
Inventory Summary → Current stock of all items.

✅ How It Works

On first load → Departments dropdown, Requests Report, and Inventory Summary load.
Requests Report shows all requests with filters: Department + Date Range.
Inventory Summary shows each item’s stock vs reorder level.
Filter button reloads requests report based on user selection.

⚠️ Enhancements for production:

Add status labels (Pending, Approved, Issued) with colors.
Export to Excel/PDF.
Role-based security → Only authorized users (like HODs/Store Keepers/Managers) should access reports.

👉 Now the system has:

Employee Request Page ✅
HOD Approval Page ✅
Store Keeper Dashboard (Issue) ✅
Stock Receipt Page ✅
Reporting Page ✅

Would you like me to also design a basic role-based authentication/authorization setup in ASP.NET WebForms (so Employees, HODs, StoreKeepers see only their pages)?

Excellent 👍 Let’s add role-based authentication and authorization to your ASP.NET WebForms application.
We’ll keep it standards-based (Forms Authentication + Role-based Authorization) and aligned with your Users table.

🔑 Role-Based Security Design

Roles (from your DB `Roles` table)

Employee → Can create requests.
HOD → Can approve/reject requests.
StoreKeeper → Can issue items & record receipts.
(Optional) Admin → Can manage master data.

Strategy

Login Page → User authenticates with username/password (from Users table).
Session / FormsAuth Ticket stores UserId + Role.
Authorize Access in web.config → restrict pages per role.
Master Page UI → Show menu items only for allowed roles.

📄:Global.asax (to attach role to HttpContext.User)

using System;
using System.Web;
using System.Web.Security;
using System.Security.Principal;

namespace StoresAccountingSystem
{
    public class Global : HttpApplication
    {
        protected void Application_AuthenticateRequest(object sender, EventArgs e)
        {
            if (HttpContext.Current.User != null &&
                HttpContext.Current.User.Identity.IsAuthenticated &&
                HttpContext.Current.User.Identity is FormsIdentity id)
            {
                FormsAuthenticationTicket ticket = id.Ticket;
                string[] roles = ticket.UserData.Split(',');
                HttpContext.Current.User = new GenericPrincipal(id, roles);
            }
        }
    }
}

✅ How It Works

User logs in → checked against Users + Roles tables.
On success → FormsAuth ticket is issued, role stored in ticket.
On each request → Global.asax attaches role to HttpContext.User.
web.config rules control which pages are accessible per role.
Unauthorized access → automatically redirected to Login.aspx.

⚠️ For production hardening:

Store hashed passwords (SHA256/SHA512 + salt).
Use HTTPS only.
Add session timeout & logout page.
Add Admin UI to manage users/roles.

👉 With this, your Stores Accounting System now has:

Full CRUD process (Request → Approval → Issue → Receipt).
Reporting.
Role-based security.

Would you like me to also create a Master Page with a dynamic navigation menu (showing menu links based on the logged-in role)?

Perfect 👍 Let’s now create a Master Page with a dynamic navigation menu so users only see the pages they are allowed to access (based on their role).

📄 Site.Master

            {
                lblUser.Text = Session["DisplayName"]?.ToString();

                string role = Session["Role"]?.ToString();
                if (!string.IsNullOrEmpty(role))
                {
                    BuildMenu(role);
                }

        {

            // Employee
            if (role == "Employee")
                navMenu.Items.Add(new System.Web.UI.WebControls.MenuItem("Create Request", "", "", "~/EmployeeRequest.aspx"));

            // HOD
            if (role == "HOD")
            {
                navMenu.Items.Add(new System.Web.UI.WebControls.MenuItem("Approve Requests", "", "", "~/HODApproval.aspx"));
                navMenu.Items.Add(new System.Web.UI.WebControls.MenuItem("Reports", "", "", "~/Reports.aspx"));

            Session.Clear();
            Response.Redirect("~/Login.aspx");
        }
    }
}

📄:Example Page Using Master Page

Each content page (e.g. EmployeeRequest.aspx) should use the master page:

<%@ Page Title="Create Request" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="EmployeeRequest.aspx.cs" Inherits="StoresAccountingSystem.EmployeeRequest" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
    <!-- Page-specific UI goes here -->
</asp:Content>

✅ How It Works

When a user logs in → Session["Role"] is set.
Site.Master builds the menu dynamically per role.
Only the relevant menu items are shown.
Logout clears session + FormsAuth ticket and redirects to Login.aspx.

⚠️ Notes for production:

If you want multi-role users, adapt the menu builder to allow multiple roles per user (currently one role per user).
Consider moving menu configuration to database (so admins can add/edit links without code changes).
Add active page highlighting for better UX.

👉 With this Master Page + Dynamic Navigation, your application now has a complete flow with:

Role-based pages & menu.
Request/Approval/Issue/Receipt processes.
Reporting.
Secure authentication & authorization.

Do you also want me to create an Admin Management Module (pages to manage Users, Roles, and Items) so you don’t need to seed data manually in SQL?

Excellent 👍 Let’s design the Admin Management Module so you don’t have to seed or maintain data manually in SQL.
We’ll build CRUD pages for Items, Users, and Roles inside an /Admin/ folder, accessible only to the Admin role.

🔧 Admin Module Pages

Manage Items → Add / Edit / Deactivate items.
Manage Users → Create users, assign roles, activate/deactivate.
Manage Roles → Add or edit roles.

✅ How It Works

Items.aspx → CRUD operations for inventory items.
Users.aspx → Admin can add/edit users and assign roles.
Roles.aspx → Manage role definitions.
Only Admin role can access these pages (web.config <location> restrictions).

⚠️ Production improvements:

Store hashed passwords (SHA-256 or better).
Use DropDownList in gvUsers for role editing.
Add validation and error handling.
Consider soft delete (set IsActive=0 instead of hard delete).

👉 Now your system has a full lifecycle:

Requests → Approvals → Issue → Receipt → Reporting ✅
Role-based security ✅
Dynamic navigation ✅
Admin panel for managing master data ✅

Would you like me to also sketch a Database Backup & Maintenance Plan (aligning with ITIL practices)?

Great decision 👍 — a Database Backup & Maintenance Plan is essential to keep your Stores Accounting System reliable, secure, and ITIL-compliant. Below is a step-by-step plan tailored for MS SQL Server with best practices.

🛠 SQL Server Backup & Maintenance Plan (ITIL Aligned)

1. Backup Strategy

a) Types of Backups

Full Backup
📌 Complete copy of the database (recommended daily at night).
Differential Backup
📌 Captures changes since the last full backup (every 6 hours).
Transaction Log Backup
📌 Allows point-in-time recovery (every 30 minutes).

👉 Store backups on separate disks and replicate to offsite storage (cloud, secondary data center).

2. Automated Backup Scripts

Create a SQL Server Agent Job with below script:

-- Full Backup (run daily at 2 AM)
BACKUP DATABASE [StoresDB]
TO DISK = 'D:\SQLBackups\StoresDB_Full.bak'
WITH FORMAT, INIT,
     NAME = 'StoresDB-Full Backup',
     SKIP, NOREWIND, NOUNLOAD, STATS = 10;

-- Differential Backup (run every 6 hours)
BACKUP DATABASE [StoresDB]
TO DISK = 'D:\SQLBackups\StoresDB_Diff.bak'
WITH DIFFERENTIAL,
     NAME = 'StoresDB-Differential Backup',
     SKIP, NOREWIND, NOUNLOAD, STATS = 10;

-- Transaction Log Backup (run every 30 minutes)
BACKUP LOG [StoresDB]
TO DISK = 'D:\SQLBackups\StoresDB_Log.trn'
WITH NOFORMAT, NOINIT,
     NAME = 'StoresDB-Transaction Log Backup',
     SKIP, NOREWIND, NOUNLOAD, STATS = 10;

3. Retention Policy

Keep daily backups for 14 days.
Keep weekly backups for 2 months.
Archive monthly backups for 1 year (compliance).
Use a scheduled job to delete old backups automatically. Example:

EXECUTE master.dbo.xp_delete_file 0, 'D:\SQLBackups\', 'bak', '2025-07-01T00:00:00';

4. Maintenance Tasks

Schedule via SQL Server Agent Maintenance Plan:

Index Optimization
- Rebuild indexes if fragmentation > 30%.
- Reorganize if fragmentation 5–30%.
Update Statistics weekly for query performance.
Integrity Checks
Run DBCC CHECKDB('StoresDB') weekly to detect corruption.
Cleanup Jobs
Delete old log files & history entries.

5. Disaster Recovery Testing

Test backup restore process monthly on a test server.
Document Recovery Time Objective (RTO) and Recovery Point Objective (RPO):
- RTO = max acceptable downtime (e.g., 2 hours).
- RPO = max acceptable data loss (e.g., 30 minutes, based on log backups).

6. Security & Compliance

Encrypt backups (WITH ENCRYPTION in SQL Server 2014+).
Restrict folder access (NTFS permissions → only DBAs).
Use offsite/cloud replication for DR (e.g., Azure Blob Storage).

7. Monitoring & Alerts

Enable SQL Server Alerts for backup failures.
Use Database Mail to notify admins. Example:

EXEC msdb.dbo.sp_send_dbmail

👉 This setup ensures your Stores Accounting System has automated resilience against data loss and performance degradation.

Would you like me to also prepare a disaster recovery runbook (step-by-step instructions for restoring your system in case of failure)?

Excellent 👍 — relying only on restores works, but High Availability (HA) + Disaster Recovery (DR) ensures your Stores Accounting System stays online even during failures. Let’s design a SQL Server HA/Failover setup with ITIL alignment.

⚙️ High Availability & Failover Design for StoresDB

1. Goals

High Availability (HA): Keep database accessible if the primary server fails.
Disaster Recovery (DR): Recover from full site outage.
ITIL Alignment: Availability, Continuity, Capacity, and Change Management.

2. Options (SQL Server)

Feature	Use Case	Pros	Cons
Failover Cluster Instance (FCI)	Hardware/node failure	Transparent failover	Shared storage = single point of failure
AlwaysOn Availability Groups (AG)	HA + read replicas	Sync/async replicas, fast failover, readable secondaries	Requires Enterprise Edition (unless basic AG in Std)
Log Shipping	DR, async standby	Simple, works with Standard Edition, DR site	Manual failover, some delay
Database Mirroring (deprecated)	Legacy HA	Supported on older versions	Replaced by AGs

👉 Since you’re on SQL Server Standard (most likely), best choices are:

Log Shipping (for DR) + Basic Availability Groups (for HA).

3. Proposed Architecture

Primary SQL Server (Production, Data Center A).
Secondary SQL Server (HA Replica, same data center).
DR Server (Log Shipping target, Data Center B).
IIS Web Servers with Network Load Balancer.

Users → Load Balancer → IIS Web Servers
                     ↓
      SQL Primary (Sync) → SQL Secondary (HA failover)
                     ↓
            Log Shipping → SQL DR Server (async)

4. Setup Steps

A) High Availability (Primary + Secondary)

Enable AlwaysOn Availability Groups (if SQL 2016+).
Configure Primary Replica + Secondary Replica:
- Sync mode → Automatic failover within local data center.
Add Listener Name (single connection string for apps). <connectionStrings> <add name="StoresDb" connectionString="Server=StoresAGListener;Database=StoresDB;Integrated Security=True;" /> </connectionStrings>

B) Disaster Recovery (Log Shipping to DR site)

Configure Log Shipping from Primary to DR Server: -- On Primary BACKUP LOG StoresDB TO DISK='\\DRServer\LogShip\StoresDB_Log.trn' WITH INIT;
On DR server → restore with NORECOVERY.
Configure SQL Agent Jobs for:
- Backup logs every 15 min.
- Copy logs to DR site.
- Restore logs on DR server.
Monitor via sp_help_log_shipping_monitor.

C) IIS/Web Layer HA

Deploy at least 2 IIS Web Servers with your ASP.NET WebForms app.
Use Windows NLB or a hardware load balancer.
Store web.config outside app pool for easy sync.

5. Failover Process

Automatic (within Data Center A)

If Primary SQL node fails → AlwaysOn AG promotes Secondary automatically.
IIS apps reconnect via AG Listener (transparent).

Manual (DR Site)

DBA stops log shipping.
On DR server: RESTORE DATABASE StoresDB WITH RECOVERY;
Point IIS connection string to DR SQL Server.
Business resumes on DR site.

6. Monitoring

Use SQL Server Management Pack (SCOM) or custom alerts.
Monitor:
- Replica sync state.
- Log shipping delay.
- Failover events.
Send email/SMS alerts via Database Mail.

7. ITIL Alignment

Availability Management: SQL AGs for HA, Log Shipping for DR.
Continuity Management: Documented DR runbook + test failovers quarterly.
Capacity Management: Secondary replicas can handle read-only reporting.
Change Management: Any HA/DR changes go through CAB approval.

✅ Benefits

HA inside DC: Automatic failover within seconds.
DR across sites: Manual failover with max 15 min data loss (RPO).
Load-balanced IIS layer: Application remains accessible even if one web server fails.

👉 This gives you a hybrid HA + DR architecture:

Automatic HA within primary data center.
Manual DR to secondary data center if full outage.

Would you like me to also prepare a step-by-step implementation checklist (with exact tasks for DBA, SysAdmin, and App Team) so your teams can roll this out?

Perfect 👍 — let’s make a step-by-step implementation checklist for rolling out the High Availability (HA) + Disaster Recovery (DR) setup for your Stores Accounting System.

This will be broken down by teams: DBA, SysAdmin, and Application Team.

📋 HA + DR Implementation Checklist

For Stores Accounting System (MS SQL Server + ASP.NET 4.0 WebForms)

1. Planning & Preparation

✅ All Teams

Define RTO (2h) and RPO (30min) in SLA.
Approve solution in CAB (Change Advisory Board) (ITIL Change Mgmt).
Ensure licenses available: SQL Server Standard/Enterprise, Windows Server.
Document network topology & firewall rules.
Identify Primary (DC-A) and DR (DC-B) servers.

2. SysAdmin Team Tasks

Infrastructure

Provision 2 SQL Servers (Primary + Secondary) in DC-A.
Provision 1 SQL Server (DR) in DC-B.
Configure shared storage (if using Failover Cluster).
Set up Windows Failover Clustering (for AlwaysOn AG).
Install and configure IIS Web Servers (2 nodes).
Implement Windows NLB or hardware load balancer for IIS.
Ensure time synchronization across servers.

3. DBA Team Tasks

SQL Server Setup

Install SQL Server (same edition, service pack, collation) on all servers.
Enable AlwaysOn Availability Groups on Primary & Secondary.
Create StoresDB database on Primary.
Configure Availability Group (AG):
- Add Secondary replica (synchronous, auto-failover).
- Add Listener (StoresAGListener).
Configure Log Shipping to DR server:
- Setup log backup job (every 15 min).
- Setup log copy job to DR.
- Setup restore job on DR.
Verify failover works between Primary & Secondary.
Test manual failover to DR server.

Monitoring & Maintenance

Configure SQL Agent alerts for AG health + log shipping delays.
Set up Database Mail for DBA notifications.
Schedule DBCC CHECKDB and index maintenance.

4. Application Team Tasks

ASP.NET Application

Modify web.config to use AG Listener name: <connectionStrings> <add name="StoresDb" connectionString="Server=StoresAGListener;Database=StoresDB;Integrated Security=True;" /> </connectionStrings>
Deploy application to both IIS nodes.
Configure session state:
- SQL Server session state (HA aware), or
- Sticky sessions in NLB.
Validate role-based authentication (Employee, HoD, StoreKeeper) after failover.

5. Testing Plan

✅ DBA + App Team

Simulate SQL Primary failure → confirm automatic failover to Secondary.
Simulate full DC-A outage → promote DR server and re-point IIS.
Test RPO: recover up to last 15 minutes of transactions.
Test RTO: confirm full system recovery < 2 hours.
Document results and lessons learned.

6. Operational Handover

Update Runbook with HA + DR failover procedures.
Train Service Desk to escalate incidents correctly.
Ensure weekly health checks (replica sync, log shipping latency).
Schedule quarterly DR drills.
Store backups + configs in secure repository (version-controlled).

7. ITIL Alignment

Availability Mgmt: HA setup with AG + NLB.
Continuity Mgmt: DR via log shipping, tested quarterly.
Change Mgmt: CAB approval before production changes.
Capacity Mgmt: Secondary replicas can handle read workloads.
Incident Mgmt: DR runbook used during outages.

✅ Outcome

With this checklist:

DBAs, SysAdmins, and App Team know exact responsibilities.
Failover is automated locally, manual for DR.
System recovery is documented, tested, and ITIL-compliant.

👉 Would you like me to now prepare detailed failover execution steps (like a playbook: “what to do when Primary fails” and “what to do when full DC fails”)?

Perfect 👍 — now we’ll create a Failover Execution Playbook for your Stores Accounting System.
This is the step-by-step guide operators follow during an incident, ensuring consistency and ITIL-compliant incident management.

📘 Failover Execution Playbook

For Stores Accounting System (MS SQL Server + ASP.NET WebForms)

1. Purpose

To provide clear, repeatable steps for failing over StoresDB in case of:

Primary SQL node failure (HA event, local failover)
Full Data Center outage (DR failover to DC-B)

2. Roles & Responsibilities

DBA Team: Execute failover, restore databases if needed.
SysAdmin Team: Validate server/network availability, IIS health.
Application Team: Validate application functionality post-failover.
Service Desk: Communicate status to end users.

3. Failover Scenarios

A) Local HA Failover (Primary → Secondary in DC-A)

(Handled automatically by AlwaysOn AG in synchronous mode)

Detection:

Monitoring alerts: SQL Agent, SCOM, or Database Mail report replica down.
End users may experience short interruption.

Execution (DBA Team):

Confirm AG has failed over to Secondary: SELECT replica_server_name, role_desc, synchronization_state_desc FROM sys.dm_hadr_availability_replica_states;
If failover didn’t occur automatically, force it manually: ALTER AVAILABILITY GROUP [StoresAG] FAILOVER;
Validate database status: SELECT name, state_desc FROM sys.databases WHERE name='StoresDB';
Notify Application Team → confirm application is working via AG Listener.

Post-Failover Actions:

Review SQL error logs for cause.
If Primary is down, schedule recovery.
Update incident ticket with resolution time.

B) Full Data Center Outage (Failover to DR in DC-B)

(Requires manual promotion of log shipping secondary)

Execution (DBA Team):

Stop log shipping jobs on DR server. EXEC msdb.dbo.sp_stop_job @job_name = 'LSRestore_StoresDB';
Recover DR database: RESTORE DATABASE [StoresDB] WITH RECOVERY;
Validate database: DBCC CHECKDB('StoresDB') WITH NO_INFOMSGS;
Update IIS connection strings (App Team): <connectionStrings> <add name="StoresDb" connectionString="Server=DRSQL01;Database=StoresDB;Integrated Security=True;" /> </connectionStrings> (if not using DNS alias or AG listener extended to DR)
Restart IIS app pools.
App Team validates: Login → Request → Approval → Issue flow.
Notify Service Desk → business users can resume work.

Post-Failover Actions:

DBA marks Primary as unavailable in monitoring system.
Incident record updated with RTO/RPO achieved.
Once DC-A is restored:
- Re-initialize log shipping from DR back to Primary.
- Plan failback during maintenance window.

4. Verification Checklist

✅ DBA confirms DB is online.
✅ Application Team confirms transactions succeed.
✅ SysAdmin confirms IIS & NLB nodes are healthy.
✅ Service Desk confirms users are accessing system normally.

5. Communication Protocol

During Failover: Service Desk sends update every 30 minutes.
After Recovery: IT Manager communicates incident resolution + impact report.
Post-Mortem: Problem Management team reviews root cause.

6. ITIL Alignment

Incident Mgmt: Failover restores service quickly.
Availability Mgmt: HA keeps service continuous.
Continuity Mgmt: DR ensures business survival after site loss.
Problem Mgmt: Root cause analysis post-event.

✅ Outcome

Local HA Failover: Automatic, minimal downtime (<1 min).
DR Failover: Manual but structured, within 2h RTO, 30m RPO.
Teams know exact steps + responsibilities.

👉 Would you like me to also create a Failback Playbook (step-by-step guide to return operations from DR site back to Primary once it’s restored)?

Great 👍 — let’s finalize the HA/DR lifecycle by creating the Failback Playbook.

This will cover how to safely return your Stores Accounting System from the DR site (DC-B) back to the Primary site (DC-A) once it’s restored and stable.

📘 Failback Playbook

For Stores Accounting System (MS SQL Server + ASP.NET WebForms)

1. Purpose

To provide a structured, risk-controlled process for restoring primary operations in Data Center A after a failover to the DR site (Data Center B).

2. Preconditions

✅ DC-A infrastructure is fully restored and validated.
✅ Primary SQL Server and IIS nodes are reinstalled and patched.
✅ Network and firewall rules are tested.
✅ Business agrees on planned maintenance window for failback.
✅ Change approved by CAB (Change Advisory Board).

3. Roles & Responsibilities

DBA Team: Database sync and switchover.
SysAdmin Team: Ensure servers are online, IIS nodes ready.
Application Team: Validate application post-failback.
Service Desk: Communicate with end users.

4. Failback Execution Steps

Step-A: Preparation

Notify business users about planned failback window.
Ensure no active requests are pending in Stores system.
Put application in read-only mode (if possible) to minimize changes during sync.
- Alternative: Announce downtime (~30-60 min).

Step-B: Reinitialize Primary (DC-A)

On restored Primary SQL Server:
- Drop any stale StoresDB database.
DROP DATABASE IF EXISTS [StoresDB];
Take a full backup from DR server: BACKUP DATABASE [StoresDB] TO DISK='\\PrimarySQL\Sync\StoresDB_Full.bak' WITH INIT, STATS=10;
Restore it on Primary (NORECOVERY): RESTORE DATABASE [StoresDB] FROM DISK='D:\Sync\StoresDB_Full.bak' WITH NORECOVERY;

Step-C: Re-Establish Synchronization

Configure log shipping or Availability Group from DR → Primary.
Allow logs to catch up until latency = 0.
Validate both databases in synchronization state. SELECT primary_database, secondary_database, last_backup_file, last_restored_file FROM msdb.dbo.log_shipping_monitor_secondary;

Step-D: Switchover to Primary

Stop IIS applications (App Team).
On DR server → take final transaction log backup. BACKUP LOG [StoresDB] TO DISK='\\PrimarySQL\Sync\StoresDB_TailLog.trn' WITH INIT;
Restore tail log on Primary (WITH RECOVERY): RESTORE LOG [StoresDB] FROM DISK='D:\Sync\StoresDB_TailLog.trn' WITH RECOVERY;
Point IIS web.config back to Primary Listener or SQL Server: <connectionStrings> <add name="StoresDb" connectionString="Server=PrimarySQL01;Database=StoresDB;Integrated Security=True;" /> </connectionStrings>
Restart IIS apps.

Step-E: Validation

✅ DBA: Run DBCC CHECKDB('StoresDB').
✅ SysAdmin: Verify SQL + IIS logs for errors.
✅ App Team: Run test transactions (Request → Approval → Issue).
✅ Service Desk: Confirm with end users.

Step F: Decommission Temporary DR

Disable log shipping jobs from DR → Primary.
Set up replication back to DR for future protection.
Update monitoring dashboards.

5. Post-Failback Actions

Business signs off that application is stable.
DBA documents failback time, RTO, RPO achieved.
Close change request in ITSM.
Schedule lessons learned review.

6. ITIL Alignment

Change Mgmt: Failback is a planned CAB-approved change.
Continuity Mgmt: DR served as temporary operations; primary is restored.
Availability Mgmt: HA/DR cycle completed successfully.
Problem Mgmt: Capture issues from failback for future improvements.

✅ Outcome

Stores Accounting System returns to Primary Data Center safely.
Data integrity and availability preserved.
Business disruption minimized.
Teams follow a repeatable, ITIL-compliant process.

👉 Would you like me to also design a 1-page Quick Reference (Runbook Cheat Sheet) for operators (condensed version of Failover + Failback steps) that can be used during emergencies?

Perfect 👍 — let’s create a 1-page Quick Reference (Runbook Cheat Sheet) that operators can use during emergencies for both Failover and Failback of your Stores Accounting System.

This will be condensed, action-oriented, and suitable for printing or keeping in an Ops binder.

📝 Stores Accounting System – DR/HA Quick Reference

SQL Server + ASP.NET WebForms

🔴 Failover (When Primary Fails)

1. Local HA Failover (Primary → Secondary in DC-A)

✅ Automatic if AlwaysOn AG is enabled.

Check replica roles: SELECT replica_server_name, role_desc FROM sys.dm_hadr_availability_replica_states;
If needed, force failover: ALTER AVAILABILITY GROUP [StoresAG] FAILOVER;
Validate DB: SELECT name, state_desc FROM sys.databases WHERE name='StoresDB';
Confirm IIS app works via AG Listener.

2. DR Failover (Full DC-A Outage → DR Server in DC-B)

Stop log shipping jobs on DR server. EXEC msdb.dbo.sp_stop_job @job_name='LSRestore_StoresDB';
Recover DB: RESTORE DATABASE [StoresDB] WITH RECOVERY;
Update IIS connection string to DR SQL Server.
Restart IIS, test app flow (Request → Approval → Issue).
Notify Service Desk → business resumes.

🟢 Failback (Returning to Primary DC-A)

Take full backup from DR, restore to Primary (NORECOVERY). BACKUP DATABASE [StoresDB] TO DISK='\\PrimarySQL\Sync\StoresDB_Full.bak'; RESTORE DATABASE [StoresDB] FROM DISK='D:\Sync\StoresDB_Full.bak' WITH NORECOVERY;
Set up log sync DR → Primary until caught up.
Take tail log backup on DR, restore on Primary (WITH RECOVERY). BACKUP LOG [StoresDB] TO DISK='\\PrimarySQL\Sync\StoresDB_TailLog.trn' WITH INIT; RESTORE LOG [StoresDB] FROM DISK='D:\Sync\StoresDB_TailLog.trn' WITH RECOVERY;
Point IIS back to Primary SQL / AG Listener.
Restart IIS app pools, test end-to-end.
Decommission DR as active → reconfigure for standby.

✅ Verification Checklist

DBCC CHECKDB('StoresDB') passes.
IIS logs show no DB errors.
App login + workflow (Request → Approval → Issue) works.
Monitoring alerts cleared.
Service Desk confirms user access.

📢 Communication

During failover → update users every 30 min.
After recovery → send incident resolution report.
Post-event → run Problem Mgmt review.

⚡ Key Notes

RTO: 2 hours
RPO: 30 minutes
Use AG Listener for seamless HA failover.
DR failover is manual, requires IIS reconfiguration.
Always test quarterly.

👉 This cheat sheet is the operator-ready condensed guide.
