Master Microservices with Spring Boot and Spring Cloud - Step 13 – Configure JPA and Initialized Data – V2

The video tutorial guides viewers through setting up an in-memory H2 database using Spring Boot and JPA. It covers adding necessary dependencies, configuring application properties, creating JPA entities, and inserting data into the database. The tutorial also addresses common errors and provides solutions. Finally, it prepares viewers for connecting a REST API to the database in the next tutorial.

What is the purpose of using an in-memory database like H2 in this tutorial?

• To enhance application security

• To permanently store data

• To temporarily store data for testing

• To replace the need for a database

Which dependency is added to communicate with the H2 database?
