Teneo/Hibernate

NOTE: the documentation for Hibernate is currently (January 2010) being transferred from the current site to the Eclipse wiki. This means that the pages in the wiki can be incomplete until the transfer is complete. For the complete documentation visit the current site: here.

The EMF - Hibernate integration supports all EMF features and standard Hibernate features. EMF objects can be persisted in most major relational databases and retrieved using an EMF resource approach or HQL queries.

The EMF - Hibernate integration is a layer over the Hibernate product. The currently used/tested Hibernate version is 3.3.2.

EMF, Hibernate and Teneo Versions

• 1.0.4: for Eclipse 3.4-3.3/EMF 2.4-2.3/hibernate 3.2/3.3.1 and jdk 1.5
• 1.1.0: Release for Eclipse 3.5/EMF 2.5/hibernate 3.2/3.3.1 and jdk 1.5
• 1.1.1/1.1.2: Maintenance Builds for Eclipse 3.5/EMF 2.5/hibernate 3.3.2 and jdk 1.5
• 1.2.0: Stable Builds for Eclipse 3.6/EMF 2.6/hibernate 3.3.2 and jdk 1.5

Note: the difference in hibernate versions between the 1.1.0 and 1.1.1 and higher builds. Hibernate introduced a binary incompatibility in version 3.3.2, forcing Teneo to adhere to this.

JPA/EJB3 Annotations

Teneo supports the full set of JPA annotations in the model (xsd or ecore) itself or in a separate XML file:

• Supported annotations: gives a complete overview of the support for JPA annotations including Hibernate annotation extensions and convenience Teneo extensions.

• Annotations format: describes in detail how annotations can be specified in the model itself or in a separate XML file. By supporting an external XML it is possible to annotate existing ecore models, so without the need to change them.

• Annotation examples: provides downloadable examples and discusses some special cases.

XML Schema Support

Teneo supports practically all XML Schema constructs which are also supported by EMF. Teneo tries to generate a sensible, practical, readable and performant database schema for a XML Schema model. It is important that the domain model concepts are also reflected in the database schema itself.

For more details on the Teneo XML Schema support, visit the following pages:

• Supported XML Schema Constructs: gives a detailed listing of the XML Schema which are supported by Teneo.
• Feature Map and Mixed Content: discusses how Teneo supports mixed content and feature maps.

CVS and Support

The Teneo source code can be found here (CVS):
