Prepmaster API is a Spring Boot application developed as a Maven project. It provides a backend solution for the Prepmaster website, a practice exam platform designed for students preparing for the exit exams in Ethiopian Universities.

• Java
• Spring Boot
• Maven
• PostgreSQL
• Render.com (API Hosting)

The following dependencies are used in this project:

• Spring Boot Web: Used for building RESTful APIs and handling HTTP requests.
• Spring Boot Data JPA: Provides support for data access using Java Persistence API (JPA) and Hibernate.
• PostgreSQL Driver: Enables connectivity between the application and the PostgreSQL database.

Prepmaster API follows the full N-tier architecture, ensuring a clear separation of concerns and modularity. The architecture consists of the following layers:

• Presentation Layer: Handles the presentation logic, including REST controllers and DTOs.
• Service Layer: Implements the business logic and coordinates the flow of data between the presentation and data access layers.
• Data Access Layer: Interacts with the PostgreSQL database using JPA repositories.

To set up the Prepmaster API locally, follow these steps:

1. Clone the repository: git clone https://github.com/your-repo/prepmaster-api.git
2. Navigate to the project directory: cd prepmaster-api
3. Build the project: mvn clean install
4. Configure the PostgreSQL database connection in the application.properties file.
5. Run the application: mvn spring-boot:run
