+# FARM Management System
+
+## Project Description
+
+FARM Management System is a comprehensive desktop application built with JavaFX for managing agricultural operations. The system provides tools for tracking production, managing employees, suppliers, and sales operations with an intuitive graphical user interface.
+
+## Features
+
+### Core Functionality
+- **User Authentication**: Secure login/signup system for admin users
+- **Production Management**: Track farm production with detailed records including:
+ - Crop types and quantities
+ - Pricing and dates
+ - Employee assignments
+ - Supplier information
+- **Employee Management**: Manage farm workforce and track employee activities
+- **Supplier Management**: Maintain supplier relationships and records
+- **Sales Operations**: Handle sales transactions and tracking
+- **Production Monitoring**: Daily production tracking and consumption monitoring
+- **Dashboard**: Visual analytics with charts and real-time counters
+- **Profile Management**: User profile and account management
+
+### Technical Features
+- **Secure Database Operations**: SQL injection prevention with parameterized queries
+- **Connection Pooling**: Efficient database connection management
+- **Input Validation**: Comprehensive form validation and sanitization
+- **Error Handling**: User-friendly error messages and exception handling
+- **Configuration Management**: Centralized configuration system
+
+## Technology Stack
+
+- **Frontend**: JavaFX 17 for desktop GUI
+- **Backend**: Java 17
+- **Database**: MySQL 8.0
+- **Build Tool**: Maven 3.6+
+- **Architecture**: Model-View-Controller (MVC) pattern
+
+## Database Schema
+
+The system uses three main tables:
+
+### `admin` Table
+- User authentication and profile information
+- Fields: id, email, password, full_name, NTele, DateBird, Age, image_path
+
+### `production` Table
+- Production records and tracking
+- Fields: id, metrage, Nom_de_race, Quantite, Qantite_Finale, Prix, Date_dentre, Nom_de_lemploye, nom_de_fournisseur, origine
+
+### `suivi_production` Table
+- Daily production monitoring
+- Fields: id, quantite_par_jour, date, consomation, emploiyee
+
+## Installation and Setup
+
+### Prerequisites
+- Java 17 or higher
+- Maven 3.6 or higher
+- MySQL 8.0 or higher
+
+### Database Setup
+1. Install and start MySQL server
+2. Create a database named `myprojectjavafx`
+3. Import the provided SQL file:
+ ```bash
+ mysql -u root -p myprojectjavafx < myprojectjavafx.sql
+ ```
+
+### Application Setup
+1. Clone the repository:
+ ```bash
+ git clone https://github.com/Saidgarnit/FARM.git
+ cd FARM
+ ```
+
+2. Configure database connection in `src/main/resources/config.properties`:
+ ```properties
+ db.url=jdbc:mysql://localhost:3306/myprojectjavafx
+ db.username=root
+ db.password=your_password
+ ```
+
+3. Build the project:
+ ```bash
+ mvn clean compile
+ ```
+
+4. Run the application:
+ ```bash
+ mvn javafx:run
+ ```
+
+## Configuration
+
+The application uses a configuration file located at `src/main/resources/config.properties`. Key settings include:
+
+- Database connection parameters
+- Connection pool settings
+- Application metadata
+- Session timeout settings
+
+## Security Features
+
+### Implemented Security Measures
+- **SQL Injection Prevention**: All database queries use parameterized statements
+- **Input Sanitization**: User inputs are sanitized before processing
+- **Password Security**: Secure password hashing with salt (for new implementations)
+- **Connection Security**: Secure database connection management
+- **Session Management**: Proper session handling and timeout
+
+### Recommended Security Enhancements
+- Implement password hashing for existing user accounts
+- Add role-based access control (RBAC)
+- Implement audit logging
+- Add data encryption for sensitive information
+- Enable HTTPS for any future web components
+
+## Development

+
+### Code Quality Guidelines
+- Follow Java naming conventions
+- Use parameterized queries for database operations
+- Implement proper exception handling
+- Add input validation for all user inputs
+- Use the provided utility classes for security operations
+
+## Testing
+
+### Running Tests
+```bash
+mvn test
+```
+
+### Manual Testing
+1. Start the application
+2. Test user authentication
+3. Verify CRUD operations for production records
+4. Test search and filtering functionality
+5. Validate input validation and error handling
+
+## Recent Improvements
+
+### Build and Configuration
+- ✅ Fixed Maven build configuration (Java 17 compatibility)
+- ✅ Removed duplicate JavaFX dependencies
+- ✅ Added proper MySQL connector dependency
+- ✅ Updated to stable JavaFX versions
+- ✅ Added configuration management system
+
+### Security Enhancements
+- ✅ Fixed SQL injection vulnerabilities
+- ✅ Added input validation and sanitization
+- ✅ Implemented proper database connection pooling
+- ✅ Added comprehensive error handling
+- ✅ Created security utilities for password management
+
+### Code Quality
+- ✅ Improved database connection management
+- ✅ Added proper resource cleanup
+- ✅ Enhanced user feedback with alerts
+- ✅ Implemented validation for user inputs
+- ✅ Added confirmation dialogs for destructive operations
+
+## Future Enhancements
+
+### Planned Features
