PROJECT STILL IN PROGRESS

Overview

This REST API was made to abstract an University Academic System. The main classes can be observed in the diagram below.

Link to acess the API: API

Technologies used

• Java Spring Boot
• Gradle
• H2 Database (development tests)
• PostgreSQL (deploy)
• JPA (to interact with the database)
• Swagger (to make the interface and documentation)
• Railway (to deploy the API in web)
