Projects

Hibernate

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, association, inheritance, polymorphism, and the Java collections framework. To allow a rapid build procedure ... [More] , 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

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 and relationships, NHibernate automatically generates SQL for loading and storing the objects. ... [More] Optionally, you can describe your mapping metadata with attributes in your source code. [Less]

JBoss Application Server

JBoss Application Server is the #1 most widely used Java application server on the market. Hundreds of professional open source developers have contributed to the JBoss Application Server over the years and community contributors are not only welcome but encouraged. In fact all JBoss employed ... [More] contributors to the JBoss Application Server were hired from the community and each of them contributed to an open source project in one way or another. [Less]

SQLAlchemy

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 persistence patterns, designed for efficient and high-performing database access, adapted into a ... [More] 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]

GlassFish

The GlassFish community is building free, open source, production-quality, enterprise software. The main deliverable is a production-quality Application Server that is also the Java EE 6 Reference Implementation. There are 2 ongoing releases of the GlassFish AppServer. GlassFish v2 is in ... [More] production and supports Java EE 5 with clustering and failover. GlassFish v3 adds a modular architecture with a very small kernel. The 3.1.2 release that supports Java EE 6 with clustering, is in production, and the 4.0 release, which will be the Java EE 7 reference implementation, is under development. TheAquarium (http://blogs.sun.com/theaquarium) reports on activity in the community. [Less]

memcached

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

Doctrine

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 an OO (object oriented) SQL-dialect called DQL inspired by Hibernates HQL. This provides developers ... [More] with a powerful alternative to SQL that maintains a maximum of flexibility without requiring needless code duplication. [Less]

XStream

XStream is a simple library to serialize objects to XML and back again. Features: Ease of use, no mappings, performance, clean XML, no modifications to classes, integration with XML libraries, full object graph support, customizable conversion strategies.

Hibernate Annotations

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

Propel

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 database. Propel enables you to perform complex queries and database manipulations without writing a single SQL clause.
