It can be embedded in Java applications or run in the client-server mode. H2 is a relational database management system written in Java.

Spring Boot has very good integration for H2. H2 is one of the popular in memory databases. Spring Boot provides Simple Configuration to switch between a real database and an in memory database like H2.Easy to use for Learning, POCs and Unit Tests.In these kind of scenarios, an in memory database provides an ideal solution.Īn in memory database is created when an application starts up and destroyed when the application is stopped. You would want to be able to run them in parallel - multiple developers might be running the tests in parallel.You don’t want them to fail when some data/schema in the database changes.Using a traditional database involves a lot of overhead.

Scenario 1 - Let’s consider a situation where you would want to do a quick POC.

Connect the application to the database by setting up a data source and a lot of other code.
