'Poseidon for UML' Version 4.0 Released

Elizabeth Graham writes "Gentleware incorporates enhanced UML 2.0 functionality into the intuitive software modeling tool.

Hamburg, Germany, 13 December 2005 - Innovative UML tool provider Gentleware AG announced today the release of version 4.0 of the market-leading modeling tool, "Poseidon for UML". With the inclusion of UML 2 capabilities in this major release, Gentleware offers the ideal modeling tool for a wide range of users. Poseidon for UML is one of the few tools to implement the underlying logic of the UML 2 standard, and the only tool to do so within a user-friendly interface.

"Our focus has always been on producing a powerful tool that's easy to use," relates Marko Boger, CEO of Gentleware AG. "There are many competing UML tools today, but our overwhelming success comes from the fact that we have managed to surpass the others in both functionality and usability." The tool itself takes only a short time to fully get into due to a clean and well-planned user interface, and it boasts the added advantage of making the UML notation simpler to use through the inherent UML rules that, for example, restrict association creation to only legal associations, ensuring the most correct model possible.

UML modeling is ever more important to software development; a study conducted in July of 2004 by BZ Research reported that over two-thirds of development managers say UML is used within their organization. The UML 2.0 standard with its enriched notation has become indispensible to this effort. "The significant advantages of using UML 2 to architect systems are undeniable," states Cris Kobryn, chair of the UML 2 standardization process in the Object Management Group (OMG). "Gentleware has taken the right approach in its development of Poseidon for UML. Developers in general and Business Process modelers in particular will be impressed with Poseidon's new UML 2 features."

These enhancements can be evaluated free of charge for 30 days or purchased at the Gentleware web site ( Among other products, commercial users may choose the Standard Edition for USD 249 or the Eclipse-integrated Professional Edition for USD 875. Gentleware also offers convenient and economical concurrent user license packages for multi-user environments.
