Hibernate, like all other object/relational mapping tools, requires metadata that governs the transformation of data from one representation to the other (and vice versa). As an option, you can now use JDK 5.0 annotations for object/relational ... [More] mapping with Hibernate 3.2. You can use annotations in addition to or as a replacement of XML mapping metadata.

Hibernate EntityManager implements: * The standard Java Persistence management API * The standard Java Persistence Query Language * The standard Java Persistence object lifecycle rules * The standard Java Persistence ... [More] configuration and packaging Hibernate EntityManager wraps the powerful and mature Hibernate Core. You can fall back to Hibernate native APIs, native SQL, and native JDBC whenever necessary. The Hibernate Java Persistence provider is the default persistence provider of the JBoss EJB 3.0 implementation and bundled with the JBoss Application Server. [Less]

JPOX provides transparent persistence of Java objects. It is a compliant implementation of the JDO1.0, JDO2.0, JDO2.1 and JPA1.0 specifications. It supports persistence to all of the major RDBMS on the market today, as well as to DB4O datastores. It ... [More] allows querying using either JDOQL, SQL or JPQL. JPOX 1.1.0 is the Reference Implementation(RI) for JDO 2, and JPOX 1.2.0 is the RI for JDO2.1. It uses OSGi technology for its plugin framework [Less]

A Java EE persistence project. It aims to be a feature-rich implementation of the persistence part of Java Community Process JSR-220 (Enterprise JavaBeans 3.0), which is known as the Java Persistence API (JPA). OpenJPA can be used as a stand-alone ... [More] POJO persistence layer, or it can be integrated into any EJB3.0 compliant container and many lightweight frameworks. [Less]

The Envers project makes it simple to version entities. The only thing required is annotating them with @Versioned. Storing historical data (versions) is completely transparent to the developer. He/she may interact with the entities as always. Not ... [More] only basic properties of an entity can be versioned, but also relations, making it possible to view parts of the database as they were at a given revision (each revision has an associated timestamp, one revision = one transaction, in which versioned data has changed). Moreover, Envers provides a straightforward interface for retrieving historical data, a criteria-like query interface, and the possibility to store additional information alongside each revision. Envers works with Hibernate and Hibernate Entity Manager. [Less]

The DataNucleus project provides products for the management of application data in a Java environment. Our aim is to provide good quality open source products to handle data in all of its forms, wherever it is stored. This goes from persistence of ... [More] data into heterogeneous datastores, to providing methods of retrieval using a range of query languages, and eventually on to the analysis of data and tools for managing data quality. DataNucleus Access Platform is the baseline product providing persistence of Java objects to a range of datastores using JDO and JPA APIs and permitting various query languages. [Less]

Utility library to implement domain objects and DAOs based on JPA and Spring.

JaQue provides an infrastructure for Microsoft LINQ like capabilities on Java platform. Using ASM, JaQue builds expression trees, which are used to build a query in domain specific technology or language, such as SQL. This way Java developers can ... [More] focus on writing application logic in the language they know - Java, regardless what the underlying technology or language is in use. JaQue to Objects and JaQue to XML are currently supported and JaQue to JPA and JaQue to JDBC are under development. [Less]
