Project Overview
The Point of Sale System is a Java desktop application built to simulate common retail operations such as processing purchases, managing products and inventory, generating receipts, and reviewing sales records. It provides separate workflows for cashiers and administrators within a single application.
Key Features
- Role-based authentication for cashiers and administrators
- Product and inventory management with CRUD operations
- Sales processing with automatic transaction recording
- Receipt generation for completed purchases
- Transaction history for reviewing previous sales
Technical Overview
Tech stack
- Java
- Java Swing
- SQLite
- JDBC
Key decisions
- Use Java Swing to build the desktop user interface.
- Use SQLite for lightweight local data persistence.
- Connect application logic and database operations through JDBC.
Architecture & approach
The application uses Java Swing for the desktop interface and JDBC to connect application logic with a SQLite database containing users, products, inventory, and transaction records.
