*Phase 1 – Analysis and Design:*
1. *Problem Statement and Business Logic:*
– Define the problem statement, which is to create an online hotel booking system.
– Specify the business logic, including user registration, room reservation, payment processing, and user feedback.
2. *Operations (CRUD):*
– Create, Read, Update, and Delete operations.
– Create, Update, and Delete for user profiles, hotel room listings, reservations, and customer feedback.
3. *Required Tables and Relationships:*
– Identify database tables such as Users, Hotels, Rooms, Reservations, and Feedback.
– Establish relationships, like a one-to-many relationship between Hotels and Rooms, and between Users and Reservations.
4. *Technologies:*
– Backend: Use a technology stack like Node.js with Express for server-side development, and a relational database system (e.g., MySQL or PostgreSQL) for data storage.
– Frontend: Employ a JavaScript framework like React or Angular for the user interface.
– Database: Utilize an Object-Relational Mapping (ORM) tool like Sequelize to interact with the database.
– Payment Processing: Integrate a payment gateway like Stripe or PayPal.
5. *Sequence Diagrams:*
– Create sequence diagrams to illustrate how different user actions, like making a reservation or leaving feedback, interact with the system.
*Phase 2 – Creating Required Tables:*
– Implement the database schema by creating tables for Users, Hotels, Rooms, Reservations, Feedback, etc.
– Populate these tables with test data to simulate real-world usage.
*Phase 3 – Developing Backend Application:*
– Develop the backend application, including routes and controllers, to handle user registration, room listing, reservation, payment processing, and feedback submission.
– Implement authentication and authorization to secure user data.
*Phase 4 – Writing JUnit Test Cases:*
– Create JUnit test cases to ensure the backend functions correctly. Test key functionalities, such as user registration, reservation creation, and payment processing.
*Phase 5 – Developing Frontend Application:*
– Develop the user interface for the hotel booking system using a frontend framework.
– Create screens for users to browse hotels, select rooms, make reservations, and provide feedback.
*Phase 6 – Establishing Communication:*
– Set up APIs for communication between the frontend and backend. These APIs will allow the frontend to retrieve hotel listings, manage reservations, and submit user feedback.
*Phase 7 – Writing Test Cases for Frontend Application (using Jest, for example):*
– Write test cases for the frontend application to ensure that user interfaces are functioning correctly.
– Test various user interactions, such as searching for hotels, making reservations, and viewing feedback forms.
Throughout the development process, it’s important to iterate and refine your application based on user feedback and evolving requirements. Collaboration and communication among team members are key to successfully implementing the hotel booking system.
