, most object databases do not support user defined primary keys, even though this is very useful in almost every application. ObjectDB supports user defined primary keys including composite primary keys

ObjectDB is highly scalable and can manage efficiently databases in a wide range of sizes, from a few Kilobytes to hundreds of Gigabytes and even Terabytes. ObjectDB can be used in small embedded single user applications as well as in heavy loaded multi threaded multi user applications. ObjectDB

Callback methods are user -defined methods that are attached to entity lifecycle events. JPA invokes these methods automatically when the corresponding events occur. Internal callback methods Internal callback methods are defined within an entity class. For example, the following entity class

. Therefore, when the ObjectDB runtime is bundled in a product that uses only signed, enhanced, persistable classes, activation by end users is unnecessary.

The fields of persistable user -defined classes (entity classes, embeddable classes, and mapped superclasses) can be classified into the following five groups: Transient fields Persistent fields Inverse ( mappedBy ) fields Primary key (ID) fields Version field The first three groups (transient

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

Entities are in-memory instances of entity classes (persistable, user -defined classes) that represent physical objects in the database. Managing an ObjectDB database with JPA requires using entities for many operations, including storing, retrieving, updating, and deleting database objects

The Jakarta Persistence Query Language (JPQL) is an object-oriented version of SQL. Users familiar with SQL should find JPQL easy to learn and use. This chapter explains how to use JPQL and the Jakarta Persistence (JPA) Criteria Query API, which provides an alternative way to build queries in
