You'll learn the basics of working on your persistence layer with Spring, and, of course, Spring Data:
Spring Data: The persistence support in Spring is now almost equivalent to Spring Data. This is a highly flexible, powerful framework you're going to use to write 99% of your persistence layer
Spring Persistence: Spring can certainly do more than just Spring Data, when it comes to persistence. JPA, direct Hibernate support, Boot, JDBC, and a variety of other technologies are well deeply supported
System Design: Beyond how you integrate with the persistence technology you're using, there's also the core, open question of how to actually architect your persistence layer correctly. I touch on that here as well.
