I got a complaint about the translation of many-to-many UML associations to SQL tables in my UMLtoSQL online service .

More specifically, the complaint was that in the translation of this UML class diagram:

The four-year SPEEDS (SPEculative and Exploratory Design in Systems Engineering) project, funded under the European Union’s 6th Framework Programme, has come to a highly successful conclusion. The SPEEDS project has resulted in the definition of a novel end-to-end design methodology, process and tool environment for model-based safety-critical embedded systems that significantly improves design quality while reducing both design cycle times and costs.

TextUML Toolkit 1.6 RC1 is now available! You can install it using the Marketplace Client or by pointing Eclipse to the update site:

If you find any problems installing this build, please let us know asap so it can be addressed before the final release.

New features

Much of the work in this release went into improving the model building infrastructure to be even more notation agnostic. That work is still ongoing and should be completed in 1.7. But there were plenty of user-facing feature additions as well:

• preconditions on operations (2986923 and 3002571)
• support for a default notation (so file extensions can be optional) (2995372)
• support for implicitly applying profiles/stereotypes (so models are less verbose) (2981580)
• support for derived properties (2928428)
• support for initial values in properties (2115439)
• advanced features (closures, constraints) are now implemented using profiles instead of metamodel extensions (2933692)

In other news

The reason it took so long for a new TextUML Toolkit release to come about was that I have been busy working on AlphaSimple, which went on public beta today. AlphaSimple is an online tool for domain-driven prototyping that currently uses TextUML as modeling notation. Thus, AlphaSimple is also the driving force behind most of the changes that happened in the 1.6 cycle, and you can try them right away by starting a guest session and studying the example projects.

The paper presents the results of three sets of controlled experiments aimed at analyzing whether UML class diagrams are more comprehensible than ER diagrams during data models maintenance. -->
