⚙️ Prerequisites

• Java Development Kit (JDK) 17 or later
• JavaFX 17 SDK
• IntelliJ IDEA (recommended) or any Java IDE

---

🚀 Installation & Setup

Option 1: IntelliJ IDEA (Recommended)

1. Clone the repository:

   git clone <repository-url>
   cd "Universty Data Management"

2. Open in IntelliJ IDEA:

   • File → Open → Select the project directory

3. Configure JavaFX SDK:

   • File → Project Structure → Libraries
   • Add JavaFX SDK library

4. Add FontAwesomeFX dependency:

   • Ensure fontawesomefx-8.9.jar is in the project classpath
   • Or add via Maven/Gradle (see below)

5. Run the application:

   • Open src/sample/Main.java
   • Right-click → Run 'Main.main()'

Option 2: Command Line

# Compile (adjust paths for your system)
javac --module-path /path/to/javafx-sdk/lib --add-modules javafx.controls,javafx.fxml \
  -cp "src" -d out src/sample/*.java

# Run
java --module-path /path/to/javafx-sdk/lib --add-modules javafx.controls,javafx.fxml \
  -cp out sample.Main

---

📖 Usage

1. Login

• Launch the application
• Enter your credentials on the login screen
• Click "Log In"

2. Dashboard

After login, you'll see the main dashboard with four management modules:

• Manage Students - Student record management
• Manage Departments - Department/category management
• Manage Course - Course record management
• Manage Professors - Professor record management

3. CRUD Operations

Each module provides four operations:

• Add - Create new records
• Edit - Update existing records (enter old data in left fields, new data in right fields)
• Search - Find records by entering search criteria
• Delete - Remove records

🔑 Login Credentials

Username	Password	Role
dtu	dtu	Standard User
a	a	Root/Admin
youssef	(empty)	Standard User

⚠️ Security Note: Credentials are hardcoded for development purposes. Do not use in production.

---

💾 Data Storage

The application uses flat text files for data persistence:

Entity	Input File	Output File
Students	student_in.txt	student_out.txt
Professors	professor_in.txt	professor_out.txt
Courses	courses_in.txt	courses_out.txt
Departments	departments_in.txt	departments_out.txt

Data Format Examples

Student Record:

Name youssef :  Dept dtu :  Lev 1 :  Ph 1

Professor Record:

mohammed:0113131:20000.0:true:false:false:false

Course Record:

112:java programming :400.0:3:150.0

Department Record:

dtu

Design Pattern

• MVC (Model-View-Controller):
  • Model: student.java, professor.java, courses.java, departments.java
  • View: FXML files
  • Controller: Controller.java, LogIn.java

⚠️ Known Issues & Limitations

Issue	Description
🔴 Hardcoded Paths	File paths are hardcoded to D:\untitled7\src\sample\ — won't work on other machines
🔴 No Build System	No Maven/Gradle — manual dependency management
🟡 Duplicate Code	CRUD logic is repeated across all entity classes
🟡 No Validation	Input validation only checks for empty fields
🟡 No Unit Tests	No test coverage
🟡 File I/O Race Conditions	Concurrent access could corrupt data
🟡 No Data Integrity	No unique constraints or referential integrity
🟢 Mixed Naming	Some fields use camelCase, others use different conventions
🟢 Commented Code	Large blocks of commented-out code throughout

---

🚀 Future Improvements

• Database Integration - Replace flat files with SQLite/MySQL
• Build System - Add Maven or Gradle build configuration
• Path Configuration - Use relative paths or configuration file
• Input Validation - Add proper field validation (phone format, score range, etc.)
• Error Handling - Implement proper error dialogs and logging
• Unit Tests - Add JUnit tests for entity classes
• Code Refactoring - Extract common CRUD logic into base class
• Search Functionality - Implement partial/fuzzy search
• Data Export - Add CSV/PDF export capability
• Authentication - Implement secure password hashing
• UI/UX - Add data tables with sorting and filtering
