Modelio-Open is a project hosting a set of open source extensions (SoaML, SysML and UML Testing Profile) for a previous version (1.2) of the Modelio Free tool . Currently, the lastest version (2.x) of Modelio modeling and generation tool is available at http://modelio.org/downloads/download-modelio.html. All extensions are downloadable at http://forge.modelio.org/projects.

** ATTENTION ** THIS PROJECT HAS MOVED TO: https://github.com/pgmodeler/pgmodeler New releases only will be available on GitHub. PostgreSQL Database Modeler, or simply pgModeler is an open source project of a CASE tool for modeling PostgreSQL that merges the classical concepts of modeling using entity-relationship diagrams with specific features that only PostgreSQL implements. The pgModeler translates the models created by the user to SQL code and apply them onto database clusters from version 8.0 to 9.1. Please, let me know how the pgModeler is working on your computer! Help to improve this project, give your feedback about the software or report any bug at "Tickets" page. Do not forget to detail the bug and if possible attach a screenshot or model database which expressed the bug. Follow the pgModeler profile on Facebook/Twitter and be up-to-date with new features, fixes and releases. https://www.facebook.com/pgmodeler https://twitter.com/pgmodeler

ODABA is an terminology-oriented database management system (TODBMS) on a high conceptual level. It provides a number of enhanced features based on natural language analysis. Terminology orientation allows designing user oriented data models. Enhanced event model and Active Data Link technology support rapid development of GUI applications. Several development, documentation, test and analyzing tools are provided in order to support developers and administrators. .NET interface and a powerful object-orjented script language (OSI) improve development efficiency.

EasyStruts provide advanced support for developing Struts web applications with Eclipse . keywords: MVC, Struts, Eclipse, Java

Umple is technology for Model-Oriented Programming. It adds abstractions such as UML associations, attributes, and state machines to object-oriented programming languages such as Java, C++, PHP and Ruby. A developer can use Umple in one of several ways. They can start with a pure model, containing only classes, associations, attributes and state machines, and then gradually add methods in one of the base languages to the Umple code base. Alternatively a developer can start with a normal program in a language like Java, and add modeling constructs in very small increments, gradually moving their system from a code-centric system from a model-centric system. Either way, Umple provides top-quality code generation. Umple is being used, for real systems. In fact the Umple compiler itself was written in Umple. Any Java, C++ or PHP project could use Umple. The UmpleOnline web app provides a quick way to explore the Umple approach. It is at http://try.umple.org

A component based programming framework. This project is aimed to support various target frameworks. A wxWidgets based GUI application is the major sample which also provides rapid database GUI design with UML import and export (db reverse engineering).

JAG - the Java Application Generator - is a 100% Java application that generates working projects containing complete, best-of-breed J2EE applications.

A toolkit to design applications using design patterns, with facility to generate code, and reverse engineering. Drag and Drop facility to create UML Class diagrams Support to write custom plug-ins for code generators and reverse engineering.

Dresden OCLallows to query arbitrary EMF-based models. It provides an advanced OCL2 Editor, a Parser, an Interpreter, and a Codegenerator for Java and SQL. WE MOVED TO GITHUB. PLEASE VISIT https://github.com/dresden-ocl/dresdenocl

SINVAS is a software engineering platform tool to support Full Life Cycle of software development, and is composed of five products. SINVAS acquires Traceability, recyclability and visibility of software development. It will help greatly to the improvement of productivity and product quality. If you send various proposals, functions and bugs of SINVAS to us, we will reflect in the ongoing product development. SINVAS Product Introduction 1) SINVAS REQ - Requirement Management : https://sourceforge.net/projects/sinvas-req/ 2) SINVAS UML - MDD-based analysis/design : https://sourceforge.net/projects/sinvas-uml/ 3) SINVAS DEV - Modeling-based development : https://sourceforge.net/projects/sinvas-dev/ 4) SINVAS TEST - Testing and Validation of software : https://sourceforge.net/projects/sinvas-test/ 5) SINVAS ALM - Management of software development projects and methodology Thank you for your continuous interest and encouragement.

With this tool you can model your software project, with the different UML diagrams.

More than just an entirely free Java code generator, It's also a development automation tool(Much more than a normal code generator). Maybe it can become your "black technology" will improve development productivity by 1.5 to 5 times, Zero coupling to your project and without changing anything. Normal code generator flow: Template → Source Code Jmr development automation flow: Template/Model/Action → Task → Source Code/Test Case/Document Template: Support Java Script(<%%> JSP-like) and Jmr Tag(set/get/for...) Model: Database Model(like Table/View), Java POJO Model, Xml File Model and includes Transform/Mapping/Convert Tool Action: A Java Class can set Java variables to template. Support any kind of project Maven, Gradle, Web, Java, Android, PHP, Python etc. Support any kind of framework spring/springMVC, hibernate, ibatis/mybatis, struts/struts2, JPA etc. Support any kind of language Java the best.

ObjectBuilder is a C++ CASE tool (CASE, refactoring, documentation generator). It lets you create, manipulate and navigate classes, class relations, class members and class methods at a high level of abstraction.

The KlassModeler is a cross platform tool for visually creating C++ classes and class relationships. It generates attractive header files as well as HTML Documentation. An intuitive user interface makes it easy to work with large, complex models.

CM3 describes a set of plugins for several UML-Tools by adding validation-mechanisms to the tool. This enables the team to setup several individual validation-rules for their models.

The power provided by OWL reasoning engines can be translated into Java applications and vice versas with this framework. A binding among OWL and Java concepts has been done in order to incorporate the semantic features of OWL into Java.

JSDAI is a toolkit for STEP (ISO 10303), the STandard for the Exchange of Product Model data, that enables linking of CAD, CAM, PDM, PLM, CAx systems. JSDAI supports the development of Express data models (ISO 10303-11) and their implementation in Java.

OWL2XMI is a java project to facilitate the creation of classes UML diagrams. It generates a XMI file from one ontology, this XMI file can be imported using UML tools such as: StarUML, ArgoUML, among others. There are available online version, Visit Proj

PLiX (Programming Language in XML) is an XML-based code-generation framework. Generators produce XML matching the PLiX.xsd schema, which can be formatted into multiple languages. Extensible formatters support C# and VB.NET in Visual Studio 2005 and 2008

PREESM provides a complete framework for fast prototyping. It generates a simulation and an optimized multiprocessor code from graph descriptions of algorithm and architecture. Please visit the project homepage at http://preesm.sourceforge.net.
