In this course, you'll explore how primary keys can be set up for the tables underlying your entities and how you can manage the configuration of individual columns in your database columns using JPA annotations. You'll learn how to perform create, read, update, and delete operations using the JPA entity manager. Once you're done with this course, you'll be able to structure your entities and their attributes based exactly on your specifications and perform basic storage and retrieval operations using JPA and Hibernate.
