Hibernate is the default JPAimplementation used by Spring Data JPA.

NOTE:Java 17 and Spring Boot 3 are required for this course.

JPAstands for Java Persistence API. This is a common Java APIused to work with Relational Databases.

Spring Data JPAis an abstraction built on top of the JPAAPIspecification.

Being an abstraction, Spring Data JPAmakes working with database entities very efficient.

Spring Data JPAeliminates a lot of the boilerplate / cerimonial code, and allows developers to focus on developing business logic.

The downside of the efficient abstraction is that accessing the database can become a mystery. Developers who just understand how to use Spring Data JPA do not understand the complexities of JDBCand Hibernate.

You will start this course with a basic demonstration of Spring Data JPA. In this section you will learn how to work with a H2 in-memory database.

You'll see how easy it is to work with Spring Data JPA. You will also begin to understand how the Hibernate interaction is being abstracted away.

Since JPAis the Java APIfor working with Relational Databases, the course takes a closer look at Relational Databases and MySQLspecifically.

MySQL is the most popular open source relational database in the world. You will learn how to configure Spring Boot to test with a H2 in-memory database and to run integration tests against a MySQLdatabase. This is a common real-world example leveraging the power of Spring and Hibernate to give you a very flexible environment.

Once we've established a persistent database, we can explore using database migration tools.

Liquibase and Flyway are two very popular database migration tools. Spring Boot supports both options. And you will learn about both options and database security best practices.

By establishing a MySQLdatabase, Spring Boot Integration Tests, and automated database migrations we can use Test Driven Development to explore the features of JDBCand Hibernate.
