Task Overview: You are required to design and implement a simple Project Management System where users can create, retrieve, update, and delete project information. The application should be built using Java 17 and Spring Boot, with an in-memory database like H2 for data persistence. Detailed Steps:

1. Project Setup: • Initialize a new Spring Boot project using Spring Initializr (https://start.spring.io/). • Include dependencies: Spring Web, Spring Data JPA, H2 Database. • Set up the project structure with appropriate packages (controllers, services, repositories, models, etc.).
2. Database Configuration: • Configure the H2 in-memory database in application.properties. • Define the schema for the 'Project' entity (attributes: id, name, description, startDate, endDate, etc.).
3. Model Creation: • Create a Project model class in the models package with annotations for JPA entity.
4. Repository Layer: • Create a ProjectRepository interface extending JpaRepository to handle data operations.
5. Service Layer: • Implement a ProjectService class to handle business logic. • Define methods for create, read, update, and delete operations.
6. Controller Layer: • Develop a ProjectController class to handle HTTP requests. • Map CRUD operations to RESTful endpoints (e.g., POST /projects, GET /projects/{id}, etc.).
7. CRUD Operations: • Create: Implement an endpoint to add a new project. • Read: Implement endpoints to retrieve all projects and a single project by ID. • Update: Implement an endpoint to update an existing project. • Delete: Implement an endpoint to delete a project by ID.
8. Exception Handling: • Implement global exception handling using @ControllerAdvice to manage exceptions and provide meaningful error messages.
9. Data Validation: • Use Spring Validation to validate input data for create and update operations.
10. Testing: • Write unit tests for service layer methods. • Write integration tests for API endpoints.
11. Documentation: • Document each API endpoint using Swagger or a similar tool.
12. Submission: • Provide a GitHub repository link containing the complete project. • Include a README file with setup instructions and API usage details.

All the steps have been followed and implemented here. A react-based front end has also been added to visualize the app better

Front-end: ReactJS - A JavaScript library for building user interfaces. Vite - A fast development build tool for modern web applications. TailwindCSS - a utility-first UI library

Back-end: Spring Boot - An open-source Java-based framework for building microservices and standalone applications.

Database: H2 - an in-memory database available inbuilt.
