EiffelStudio is an Integrated Development Environment (IDE) that provides comprehensive facilities to programmers. It offers a comprehensive suite of tools that enable programmers to produce correct, reliable, and maintainable software while keeping control of the development process. If you want to create fast, robust, scalable applications, then EiffelStudio™ will offer you a cost-effective solution. Imagine being able to model your system as you think – capturing your requirements and your thought processes with EiffelStudio. When ready to design, you build upon the model you just created, still with EiffelStudio. Then you implement with EiffelStudio. You never need to throw anything out and start over. You don’t need extra tools to go back and safely make changes in your architecture. Roundtrip engineering? It’s built in by design. Testing, metrics and productivity tools? They’re built in. EiffelStudio accommodates quickly and efficiently new thoughts and changes.

This BlueJ-Extension is developed by three student assistants of the lecture "Programming II" at Saarland University. It is designed especially for the students of this lecture, but useable by others too.

A 100% pure Java Swing ASN.1 analysis utility for inspecting arbitrary BER-encoded data files. It allows inspection of data with unknown structure, can drill down to any nesting level and allows to interpret embedded OCTET STRING data recursively.

A openArchitectureWare based Generator for deriving a WS-Agreement document from a formal description of a (Web-)Service and its associated assertions (SLO) to Quality Of Service (QoS). You can use predefined QoS parameters as well as introduce new ones.

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).

Dinjam is an opensource, crossplatform (data) modeller especially intended for educational use. It is highly extensible through a sophisticated plugin mechanism.

This Project offers different model operations for the Eclipse Modeling Framework, such as comparison, difference calculation, merging and a unification of EMF models.

Konzept is a small class diagram editor. Major design goal was usability. The project was inspired by the static diagram editor of the Toolkit of Conceptual Modelling. Konzept is a pure Qt application written in Python.

OSLO stands for Open Source Library for OCL. It's base on the Kent OCL Library from the University of Kent.

ParTeG (PARtition TEst Generator) handles UML state machines, UML class diagrams and their OCL expressions. The OCL expressions are evaluated to find input parameter partitions. The boundaries of these partitions are used to generate test cases.

Red Chili Recipe Manager

A case study regarding the entire software development process for education in Software Engineering under consideration of general Software Engineering concepts and design patterns

is a loadable application for the jrc-framework, that helps managing db schema. Support for scanning of db-schema, export/import to/from XML, creation and versionizing of db-schema. Column-Definitions are domainbased and the GUI supports drag&drop.

The Sequence Diagram / MSC Generator is a tool to generate Sequence Diagrams from a textual description. The diagrams (bmp, png, wmf, and emf) are conform to UML2 standard (Sequence Diagrams) und to SDL standard (Message Sequence Chart).

System Map is a utility for software developers that want to create well structured software products that are understood by all stakeholders from business to developer. It allows to: - Create "System Maps" to describe software products - Decompose systems deeply Also, it has some cool goodies: - Image viewer for linked wireframes - Track development progress - Trace the specification into the source code And it’s a team player: - System Maps can be exported to MS Word or as image - Freemind is very tightly integrated since it’s a great decomposer as well

This project aims to create an EMF Ecore metamodel, code templates and a workflow for automatically generating certain Typo3 extensions. It contains an example instance for the creation of a developer garden Typo3 extension.

UMLMDA provides a set of java tools to read UML models from ArgoUML, Rational Rose, RSM or XMI and to setup generators with jsp based templates to generate code from the models. Based on this tools a MDA-Framework is developed for business applications.

W2g is a framework for building web-based applications such as online databases, intranet portals or CRM systems. It has a object-oriented design and includes a session management, a template engine and a persistency engine based on Apache and MySQL.
