Tiburon/C++Builder - soon with live UML modeling
In Project Tiburon, the next version of C++Builder will have live code and UML modeling. This means you can work in the source code, work in the UML model, and move back and forth with full, live synchronization - "the code is the model, the model is the code".
C++Builder will include support for the Class, Use Case, Sequence, Collaboration, Component, Deployment, Statechart, and Activity diagrams.
