Hibernate is a powerful, high performance object/relational persistence and query service for Java. It lets you develop persistent objects following common Java idiom, including composition ... [More] , association, inheritance, polymorphism, and the Java collections framework. To allow a rapid build procedure, Hibernate rejects the use of code generation or bytecode processing. Instead, runtime reflection is used and SQL generation occurs at system startup time. It supports Oracle, DB2, MySQL, PostgreSQL, Sybase, Interbase, Microsoft SQL Server, Mckoi SQL, Progress, SAP DB, and HypersonicSQL. [Less]

NHibernate is a port of Hibernate Core for Java to the .NET Framework. It handles persisting plain .NET objects to and from an underlying relational database. Given an XML description of your entities ... [More] and relationships, NHibernate automatically generates SQL for loading and storing the objects.

SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL. It provides a full suite of well known enterprise-level ... [More] persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language. SQL databases behave less and less like object collections the more size and performance start to matter; object collections behave less and less like tables and rows the more abstraction starts to matter. SQLAlchemy aims to accommodate both of these principles. [Less]

The GlassFish community is building free, open source, production-quality, enterprise software. The main deliverables is a production-quality Application Server that is also the Java EE 5 Reference ... [More] Implementation. There are 3 ongoing releases of the GlassFish AppServer. GlassFish v1 is in production. GlassFish v2 adds clustering, failover, features and performance and is close to beta3. GlassFish v3 adds a modular architecture with a very small kernel and is in early technology preview. TheAquarium (http://blogs.sun.com/theaquarium) reports on activity in the community. [Less]

Doctrine is an ORM (object relational mapper) for PHP that sits on top of a powerful DBAL (database abstraction layer). One of its key features is the ability to optionally write database queries in ... [More] an OO (object oriented) SQL-dialect called DQL inspired by Hibernates HQL. This provides developers with a powerful alternative to SQL that maintains a maximum of flexibility without requiring needless code duplication. [Less]

Propel is an object persistence and query service -- which means that Propel provides a system for storing objects to a database and a system for searching for and restoring the objects from the ... [More] database. Propel enables you to perform complex queries and database manipulations without writing a single SQL clause. [Less]

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 ... [More] use JDK 5.0 annotations for object/relational mapping with Hibernate 3.2. You can use annotations in addition to or as a replacement of XML mapping metadata.
