With Tau 3.0, engineers can graphically design large software architectures for applications ranging from satellite systems to online retail applications. Development infrastructure is highlighted for SOA enablement, including C#, Java service specifications, and Java Stub generation.

"We're supporting those pieces of SOA that are already starting to come into focus such as WSDL and UDDI," as well as SOA concepts, said Scott McCorkle, Telelogic director of product marketing.

Version 3.0 offers round-trip code support for Java 5, C#, and C++, including automated code generation, code-to-model import, and synchronization between the model and the resulting software code.

Integration is enabled with the Eclipse and .Net environments, including tighter links to Visual Studio. Tau users can use Visual Studio .Net project files, McCorkle said. Legacy application reuse is featured as well, through architectural reverse-engineering and inspection.

Also, Java Archive (JAR) files can be dragged and dropped into the Tau workspace. Automatic import of JavaServer Pages and HTML pages is featured as well. Users also can import legacy models developed in Borland Together and Rational Rose. Links to Telelogic Doors enables requirements traceability.
