Real Time Developer Studio is a tool dedicated to the specification and the design of real time and embedded applications based on standard and public graphical languages such as SDL (Specification and Description Language), SDL-RT, and UML (Unified Modeling Language). SDL-RT is a combination of UML, SDL, C, and C++ standards dedicated to real time and embedded application modeling. It is a UML real time profile in which each service of the real time operating system has a dedicated graphical representation such as semaphores, timers, messages (sometimes based on signals or events), message queues, and library of active and passive classes, architecture of tasks or threads, and detailed finite state machines integrating C and C++ code. Real time developers find their way easily because all these concepts are familiar to them.

Overture is a community-based project developing the next generation of open-source tools to support modelling and analysis in the design of computer-based systems. Overture supports VDM: The Vienna Development Method, a set of modelling techniques with a long and successful history of industrial application and research. Overture is an integrated development environment (IDE) for developing VDM models. The Overture tools are written entirely in Java and build on top of the Eclipse platform.

MicroOLAP Database Designer for MySQL is a visual development system intended for database design, modeling, creation, modification and reverse engineering in an easy and powerful way. MicroOLAP Database Designer for MySQL allows you to construct your database in easy-to-understand visual environment by working with graphical representation of tables, columns, relations and so on. Finally you will get Physical Entity Relationship Model (ER Model) that can be exported in SQL script, or directly built on working MySQL database server.

Leap SE is a CASE tool that turns system requirements directly into object models for software development. More than a Requirements Management application, Leap SE shortens the systems development lifecycle and accelerates rapid application development (RAD).

vfThreaded-x86 is the only tool that gives you the precise information you need to make sure that your parallelized software will work correctly and have the highest performance on your multicore x86 machine.

The miUML (pronounced my-UML) project is centered around two key goals. First and foremost is to provide an open executable UML metamodel and API hub around which a combination of free and proprietary development tools may be contributed. So nothing prevents miUML from becoming your-UML. Second is to create a metamodel that supports high performance code generation while preserving platform independence and the high level of abstraction necessary to support complex requirements analysis.

TerraER is a free, open-source application that makes the understanding of data modeling much easier. The tool is addressed to academics, specially to support modeling database courses.

Professional diagramming, flowcharting, and design tool. Uniquely tailored for easy use with little or no training required. Create any type of block or flow diagrams. Use built in shapes and arrowheads or create your own. Contains all the features of expensive packages such as full zoom, OLE connectivity, poster printing, graphics import and export. Creates diagrams by stamping out shapes on your layout, adding any of a variety of text styles, and connecting the shapes with smart connecting lines that maintain flows and relationships. Also includes high end features such as full pan and zoom, poster printing, linking diagrams into documents, curves, importing clip art, and exporting web graphics. Powerful grid and alignment aids keep your diagram attractive. Everything from shapes to styles to diagram templates to the user interface is highly customizable so you can design your own diagram types.
