db4o

db4o is an object database available for Java and for .NET, including CompactFramework and Mono. Features include ACID transactions, automatic class schema recognition, Native Queries, query-by-example, S.O.D.A. object querying API, callback methods, memory files, cascade-on-delete and ... [More] cascade-on-update. db4o runs in embedded local mode and in multi-transactional client/server mode. [Less]

Roma Meta Framework

Roma is an Open Source initiative to make Java application development easy. The approach is totally DDD: let's think to the domain of your application and Roma will make the rest: persistence (database), presentation (HTML + Ajax), logging, user management, sessions, workflow, scheduler, etc. ... [More] Roma is a Meta Framework namely a tool that aims to remove dependencies between your application code and frameworks and tools you use. This allows you to change the technology at zero cost without any changes to your application code. Roma is also a MDA implementation since takes its concepts and philosophy but it's totally based on POJOs without to learn other micro languages and complex standards. [Less]

KiokuDB

KiokuDB is a persistent object graph manager for Perl. It uses multiple backends and layers on Moose's introspection and Search::GIN for indexing.

NeoDatis ODB

NeoDatis ODB is a new generation Object Oriented Database. ODB is a real transparent persistence layer that allows anyone to persist native objects with a single line of code. Runs on Java and .net. The ODB runtime is less than 400k and is distributed as a single jar/dll that can easily be packaged in any type of application.

ProActive

ProActive is the Java GRID and Cloud middleware library (with Open Source code under GPL license) for parallel, distributed and multi-threaded computing. With a reduced set of simple primitives, ProActive provides a comprehensive API to simplify the programming of Grid Computing ... [More] applications: distributed on Local Area Network (LAN), on clusters of workstations, or on Internet GRIDs and Clouds. ProActive is only made of standard Java classes, and requires no changes to the Java Virtual Machine, no preprocessing or compiler modification, leaving programmers to write standard Java code.

vgsdk

vgSDK, a shortcut for Versatile Graphical Software Development Kit, consists of a set of cross-platform C++ libraries which provides a complete framework for doing graphical related tasks.

Mocha

Mocha is a library for mocking and stubbing using a syntax like that of JMock, and SchMock. Most commonly Mocha is used in conjunction with Test::Unit, but it can be used in other contexts. One of its main advantages is that it allows you to mock and stub methods on real (non-mock) classes and ... [More] instances. You can for example stub ActiveRecord instance methods like create, save, destroy and even class methods like find to avoid hitting the database in unit tests. Mocha provides a unified, simple and readable syntax for both traditional mocking and for mocking with real objects. Mocha has been harvested from projects at Reevoo by me (James) and my colleagues Ben, Chris and Paul. Mocha is in use on real-world Rails projects. [Less]

gedemin

The Gedemin project is an open-sourced, object oriented, post relational rapid application development (RAD) tool especially aimed for creating of business ERP/MRP database systems.

Prevayler

"Database in memoriam" Prevayler is an object-prevalence persistence framework for Java (though implementations for other languages exist)

Virtual Object System (VOS)

VOS is a library and network protocol for interlinked object structures, which can be easily distributed over networks. Notifications of changes are automatically sent to other applications/clients. VOS simplifies concurrent asynchronous programming, both within the same process or distributed ... [More] over the network. Revision control (versions), access control, and other important features are built in. VOS object messaging also allows access from multiple languages. VOS forms the basis for several applications including multiuser 3D virtual reality, web content management, and any other application requiring an infrastructure for distributed, dynamic data structures. A multipurpose GUI client application for a combined 3D/2D/WIMP browsing and development environment is available. [Less]
