Open Source Object-Relational Mapping (ORM) Software

Hibernate is an Object/Relational Mapper tool. It's very popular among Java applications and implements the Java Persistence API. Hibernate ORM enables developers to more easily write applications whose data outlives the application process. As an Object/Relational Mapping (ORM) framework, Hibernate is concerned with data persistence as it applies to relational databases (via JDBC).

AutoDAO is a Generic DAO on steroids implementation for Java with Hibernate support, annotation-driven configuration, tight Spring Framework integration and zero persistence code required for most common query types.

Fakoli is an entity-based Rapid Application Development framework for PHP. In addition to the core framework, Fakoli/CMS can be used to provide component-based Content Management functionality for your Fakoli application.

A powerful 100% JAVA flat file processing ORM framework. Giving the ability to abstract the processing of flat files from business logic, using Hibernate style mapping constructs. Supports fixed length and delimited (e.g CSV) file formats.

FRESHHH DCLPS can be considered an object relational mapping system ORM framework. It is robust well structured web oriented programming system that allows to create web systems (web sites) just by coding javascript. That is possible cause it uses a few server php script files that are requested by javascript to get some results. The key of this system is its structure that has to deal with nested tree objects and how it is implemented in the relational database.

FSP is a simple persistence framework for relational database access from java classes.

MILK is a lightweight Java database framework. Its main target is to simplify database development providing an easy-to-use API to run SQL queries and a slim configurable ORM.

MockSqlBuilder uses mock objects and method interception to build SQL queries in an OOP fashion. Instead of strings (like HQL or plain text), MockSqlBuilder uses the data object's and their methods to record and construct a query.

The intension of the interbreed project is combine some of the promising new technologies (like Grid, noSQL Database Cassandra, OSGI and MapAndReduce) into one server architecture and ease the development of modern high scalability, high performance applications. The Api based upon easy to use annotationed pojo's to encapsulate the complexity of this modern technologies. The goal is the make programming noSQL, MapAndReduce and DistributedExecution in a high scalar environment as easy as writing total standard JPA,EJB 3.0 applications.

jPersist is an object-relational persistence API with automatic mapping, and based on the ActiveRecord and DataMapper patterns. jWebApp is an MVC web application framework. Both are configuration and annotation free and can be learned in minutes

Reusable is a JPA ORM like Hibernate. But with focus on speed, speed, speed and development speed. Hibernate is like ANT - you can do everything. Reusable is like Maven - you cant do everything, but the development speed is greater.

A framework designed to run multiple advanced applications on the same code base. It can be used as a library of useful classes for existing code, or a complete end-to-end framework for new applications. It is mature, stable and actively developed.
