The eStore application follows a classic Model-View-Controller (MVC) pattern, albeit with a more traditional Java Servlet/JSP implementation. The JSP Views serve as the presentation layer, responsible for rendering the user interface and capturing user input. The LoginServlet acts as the central controller, handling incoming web requests, delegating business logic to the service layer, and managing navigation by forwarding to the appropriate JSP views. The CustomerServiceImpl and OrderServiceImpl components encapsulate the core business logic for customer and order management, respectively. These service components interact with their corresponding Data Access Objects (DAOs), CustomerDaoImpl and OrderDaoImpl, to persist and retrieve data from the underlying database. All layers heavily rely on the Data Models (Beans) to transfer data throughout the application.
The user interface components responsible for rendering dynamic web pages, displaying product information, user forms (login, registration), and the shopping cart. They handle user input and present application data.

Acts as the primary controller for handling web requests related to user authentication and navigation. It receives HTTP requests, delegates business logic to the service layer, and manages the flow of control by forwarding to appropriate JSP views.
