To access relational databases using the Java Persistence API (JPA) you will need an Object Relational Mapping (ORM) tool, such as Hibernate, TopLink, EclipseLink, Open JPA or DataNucleus. The DataNucleus ORM implementation supports also the Java Data Objects (JDO) API . ObjectDB is a full featured

The Java Persistence API (JPA) provides various ways to retrieve objects from the database. The retrieval of objects does not require an active transaction because it does not change the content of the database. The persistence context serves as a cache of retrieved entity objects. If a requested

This chapter explains how to manage ObjectDB databases using the Java Persistence API (JPA). The first two pages introduce basic JPA interfaces and concepts: The next section explains how to use JPA for database CRUD operations: More advanced topics (e.g. locking and events) are discussed in the last section:

Welcome to ObjectDB for Java/JPA Developer's Guide. Here you can learn how to develop database applications using ObjectDB and JPA (Java Persistence API ). The main purpose of this guide is to make you productive with ObjectDB and JPA in a short time. Guide Structure Demonstrates basic database

Working with the Java Persistence API (JPA) consists of using the following interfaces: Overview A connection to a database is represented by an EntityManager instance, which also provides functionality for performing operations on a database. Many applications require multiple database
