Gaming Coffee - JavaFX Café Management System

Project Overview

“Gaming Coffee” is a desktop application built using JavaFX 19+ and Java 17, designed as a management system tailored for gaming cafés. It integrates order processing, session tracking, menu management, and sales analytics into a clean GUI desktop experience. The app uses SQLite 3.x as an embedded local database. It showcases a polished frontend linked to a simple backend via JDBC, supporting real‑time usage and local data persistence

Tech Stack & Architecture

LayerTechnologies & Tools

UI / FrontendJavaFX 19+, FXML Scenes via Scene Builder, CSS styling

Core LogicJava 17 with JDBC-based data access layer

DatabaseSQLite 3.x embedded (single-file .db)

Design ToolsFXML Scene Builder, SQLite Browser

Build & RunMaven wrapper (mvnw javafx:run), .bat & .sh launchers

It follows a simplified MVC pattern: controllers manage interactions between FXML-based views and service classes, which handle business logic and data persistence using JDBC.

Key Features

(Based on the README feature list)

Secure User Login: Role‑based authentication (Admin vs Employee), session handling, and password encryption/validation.

Menu Management: CRUD operations for food & beverage items—with categorization and price control.

Best Practices & Engineering Highlights

UI Separation (MVC), Modular Design: FXML + controller classes promote clean separation between UI design and business logic.

Structured Error Handling: Uses try‑with‑resources for database connections, with user-friendly error dialogs in JavaFX.

Input Validation: UI fields validated via JavaFX controls or custom utility classes before processing orders or login.

Transactions & Resource Cleanup: JDBC schema creation and cleanup handled responsibly to avoid data corruption.

Source Control & Documentation: Every launch option included (.bat, .sh), and step-by-step usage guides present in README for Linux/macOS/Windows
