When developing enterprise applications, Spring programmers typically prefer writing data-centric code against a lightweight in-memory database, such as H2 rather than running an enterprise database server such as Oracle, or MySQL. Out of the box, Spring Boot is very easy to use with the H2 Database. In-memory databases are useful in the early development stages […]Continue reading
