Look inside

BestInsurance, an insurance company, has an online portal with a newly built application for providing features it hopes will attract new customers. As a backend developer, it’s your job to create the persistence layer for the application. You’ll define the database tables and configure a Liquibase changelog to automatically create the tables using SQL. This will allow you to track and manage database versions in order to avoid data loss in production when you change the model. To persist your data, you’ll map Java classes to the database tables using Spring JPA, then implement the basic create, read, update, and delete (CRUD) operations through the JPA repositories for the persistent entities. To verify your mapping is correct, you’ll implement unit testing with JUnit 5 tests, TestContainers, and a PostgreSQL database.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
