Database Application Development

To design and develop a database application for a Store, Vendor, or Finance Management System. This simulation focuses on schema design, data entry forms, and transactional integrity.

Theory & Concepts

1. Introduction

A **Database Application** is a computer program whose primary purpose is to enter and retrieve information from a computerized database. While DBMS is the backend engine, the Application is the frontend interface that users interact with.

2. Application Components

  • User Interface (UI): Forms for data entry and reports for viewing data.
  • Application Logic: Validations and business rules (e.g., "Cannot sell more items than in stock").
  • Backend Database: Tables that store the persistent data.

3. Case Study: Components

Store Management

  • Tables: Products, Inventory, Sales
  • Goal: Track stock levels and daily sales.

Vendor Management

  • Tables: Vendors, PurchaseOrders, Supplies
  • Goal: Manage supplier relationships and orders.

Finance Management

  • Tables: Accounts, Transactions, Ledger
  • Goal: Track income, expenses, and balance.

4. Summary

Building a database application requires understanding the "Business Logic" of the domain. In this experiment, you will see how a high-level action like "Sell Item" translates into multiple low-level SQL operations (Insert into Sales, Update Inventory).

Procedure

1

Select Module

Choose the system you want to simulate (Store, Vendor, or Finance).

2

Master Data Entry

Use the forms to add base data (e.g., Create new Products in Store).

3

Process Transactions

Perform actions like "Generate Bill" and observe how the underlying tables change automatically.
