This chapter introduced the basic principles of JPA with ObjectDB. For more details, see the other chapters in this manual. To start using ObjectDB immediately, follow one of the tutorials below to create and run the example program from this chapter: These tutorials explain how to run the example

This chapter explains how to manage ObjectDB databases by using Jakarta Persistence (JPA). The first two pages introduce basic JPA interfaces and concepts: The next section explains how to use JPA for database CRUD ( create , read, update, and delete) operations: The final section discusses advanced topics, such as locking and events:
