Open Source BSD Object-Relational Mapping (ORM) Software

Essential ORM Modeler allows you to model your application using an extension of UML class models, generating code for distinct ORM frameworks (JPA, SQLAlchemy or Ruby´s ActiveRecord). The notation, based on persistence patterns, is platform independent. This tool is a plugin of eclipse.

The NOAP toolkit provides a collection of utilities to use for slightly more exotic development on the Common Language Infrastructure. NOAP includes a fast ORM, an Objective-C compiler for .NET, and much more. See the Web site for more information.

The project is still under development. There is a limited version which will be released for beta users soon. The databases that will be initially supported are oracle and mysql for now.

This project deals with the integration of morphia into SpringRoo's rapid development tool

This project was the result of working on systems constrained to versions of Java < 1.5 and including a great deal of code dealing with object persistence. This project was essentially a proof-of-concept to determine whether or not I could create, essentially, an alternative to JPA that did not rely on annotations. I was able to create a working system, and a fairly lightweight one at that, but it would require a great deal of work to be production ready.

Better SQL in java! Offering a seamless java class mapping and SQL-like domain-specific language implemented for number of commercial and open-source DBMS

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.
