📖 Description

• This project is a full stack CRUD web application built using a traditional Java EE approach.
• It implements a server-side architecture based on Servlets for request handling and JSP for dynamic content rendering.
• The application connects to a MySQL database using JDBC, enabling persistent data storage and retrieval. Users can interact with the system through a web interface to manage records efficiently.
• This project reflects fundamental concepts of backend development before modern frameworks like Spring Boot, focusing on low-level control of request handling, database communication, and application flow.

⚙️ Features

• Create records
• Read data from database
• Update existing records
• Delete records
• Server-side rendering with JSP
• Form handling with Servlets
• Direct database access via JDBC
• MVC-inspired structure

🏗️ Architecture

• Controller Layer
• Implemented using Servlets to handle HTTP requests and responses
• View Layer
• JSP pages with JSTL for dynamic content rendering
• Model Layer
• Java classes representing application data
• Data Access Layer
• JDBC-based interaction with MySQL database

🗄️ Database

• The project uses a MySQL database connected via JDBC.
• Database configuration is handled manually through connection parameters in the application code.
