Persistence Frameworks

ammentos

A lightweight persistence framework for Java (JDK5.0 or later). Extremely simple to use, works whith annotations, does not require any configuration/mapping file, runs whith any JDBC compliant database (no SQL dialects to configure) and supports multi-device persistence.

 

xorm

XORM is an extensible object-relational mapping layer for Java applications

 

apache-openjpa

It is a feature-rich implementation of the persistence part of Enterprise Java Beans 3.0, also known as the Java Persistence API (JPA), and is available under the terms of the Apache Software License. OpenJPA can be used as a stand-alone POJO persistence layer, or it can be integrated into any EJB3.0 compliant container and many lightweight frameworks.

 

simpleorm

SimpleORM is Java Object Relational Mapping open source project (Apache style licence). It provides a simple but effective implementation of object/relational mapping on top of JDBC at low cost and low overhead. Not even an XML file to configure!

 

tjdo

TriActive JDO (TJDO) is an open source implementation of Sun's JDO specification (JSR 12), designed to support transparent persistence using any JDBC-compliant database. TJDO has been deployed and running successfully in many commercial installations since 2001.

 

jpersist

jPersist is an extremely powerful object-relational database persistence API that manages to avoid the need for configuration and annotation; mapping is automatic. It uses JDBC, and can work with any relational database and any type of connection resource. It uses information obtained from the database to handle mapping between the database and Java objects, so mapping configuration is not needed, and annotation is not needed. In fact, there is no configuration needed at all.

 

smyle

Simple data storage API to help developers to focus on their applications instead of writing JDBC code.

 

pbeans

pBeans is a Java based persistence framework and an Object/Relational (O/R) database mapping layer. It is designed to be simple to use and completely automated.
