Factory Management System (FMS)

This project is an enterprise-level management software developed as a final project for the CME 2210 Object-Oriented Analysis and Design course at Dokuz Eylül University. It aims to optimize factory operations through a role-based modular system and automated workflows.

🚀 How to Run (Step-by-Step)

Follow these steps to run the project on your local machine:

1. Install Java: Ensure you have Java Development Kit (JDK) installed (Version 8 or higher is recommended).
2. Download the Project: Download this repository as a ZIP file or clone it using Git.
3. Prepare Data Files: Ensure the .csv files (e.g., employee_data.csv, stock_data.csv) are in the same directory as the source code.
4. Compile the Project: Open your terminal, navigate to the folder, and run: javac MainMenuSystem.java
5. Run the Application: Type the following command to start the console interface: java MainMenuSystem

💻 System Architecture & Roles

The system is built on a Three-Layer Architecture (Presentation, Application, and Data) to ensure a clear separation of concerns. It implements Role-Based Access Control (RBAC) to provide unique functionalities tailored to different user types.

👤 User Roles

• Manager: High-level access for overseeing factory operations, including production monitoring, performance reviews, and stock management.
• Employee: Focused on personal workflow, including payroll monitoring, shift schedules, and submitting leave requests.
• Customer: External interface for commercial interaction, allowing users to place orders and track status.

🛠 Technical Implementation Details

Object-Oriented Design (OOAD)

The software is a direct implementation of rigorous design phases, including Use Case, Class, and Sequence diagrams.

• Encapsulation: Sensitive user and operational data are protected within classes like PersonalInfo and User.
• Inheritance: A clean class hierarchy where Manager, Employee, and Customer inherit from an abstract User base class.
• Polymorphism: Runtime dispatch handles role-specific behaviors within the shared menu system.

Data Management & Persistence

Instead of a traditional SQL database, this system utilizes a custom Flat-File Database logic:

• DataService: A centralized utility class responsible for all input/output operations.
• CSV Processing: High-performance data handling using Java's BufferedReader and FileWriter.
• Persistence: All operational changes are immediately synchronized with local .csv files.

🔮 Future Improvements

• Transitioning from CSV files to a relational database like SQLite or MySQL.
• Development of a Graphical User Interface (GUI) using Java Swing or JavaFX.
• Implementation of advanced encryption and secure logging mechanisms.
