The Java Data Objects (JDO) is another standard for accessing persistent data in databases, using plain old Java objects (POJO) to represent the object model. Unlike Java Persistence API (JPA), which is designated to be used with relational databases, JDO is designated to be used

An entity class is a user-defined class whose instances can be stored in a database. To store data in an ObjectDB database using Jakarta Persistence (JPA), you define entity classes that represent your application's data object model. This chapter contains the following sections:
