• MySQL JDBC Driver (mysql-connector-java)
• IDE with Java support (VS Code, IntelliJ IDEA, Eclipse)

🚀 Setup Instructions

1. Database Setup

1. Install MySQL Server on your system
2. Create the database:

   CREATE DATABASE furever;

3. Import the schema:

   mysql -u root -p furever < furever.sql

2. Project Configuration

1. Clone or download the project files
2. Add MySQL JDBC Driver to your classpath:
   • Download mysql-connector-java-8.0.x.jar
   • Add to your project's classpath

🏗️ System Architecture

Design Patterns Used

• MVC Pattern: Separation of models, views (dashboards), and controllers (CRUD)
• Singleton Pattern: Database connection management
• DAO Pattern: Data access object pattern for database operations

Database Design

• Normalized schema with proper foreign key relationships
• Referential integrity maintained across all tables
• Optimized indexes for better query performance

Error Handling

• Input validation for all user inputs
• Database error handling with meaningful messages
• Connection management with automatic cleanup
• Exception handling throughout the application

🔧 Troubleshooting

Common Issues

1. Database Connection Failed

   • Check MySQL service is running
   • Verify database credentials in DbConnection.java
   • Ensure database furever exists

2. ClassNotFoundException: MySQL Driver

   • Add mysql-connector-java.jar to classpath
   • Verify JDBC driver version compatibility

3. Access Denied for User

   • Check MySQL user permissions
   • Update password in DbConnection.java

4. Table Doesn't Exist

   • Import the furever.sql file
   • Check database name is correct

Performance Tips

• Connection Pooling: For production use, implement connection pooling
• Batch Operations: For bulk data operations, use batch processing
• Index Optimization: Monitor query performance and add indexes as needed

📈 Future Enhancements

• Web-based interface
• Email notifications for adoption updates
• Photo upload functionality
• Advanced reporting and analytics
• Multi-location support
• Mobile application
