Aspire Developer to Software Architect Software Architect Track 2: Database Developer

In this course, you'll explore the various kinds of relationships that you might want to express using JPA annotations and how these relationships map to relational table design. You'll examine unidirectional as well as bidirectional one-to-one, one-to-many, many-to-one, and many-to-many relationships.

Once you're done with this course, you'll be able to model and express real-world relationships between your entities using JPA annotations. Finally, you'll learn how to finely manipulate how you want these relationships configured using underlying database tables.
