Here is a web reference to the presentation "MDA and OptimalJ" by Bast and Epstein<\a>
at the OMG tech meeting in Anaheim CA Feb 2004.
'MDA and OptimalJ' emphasizes MDA goals and how UML2/MDA proponents expect to transform the software develoment process (and your jobs:-). This presentation is very general (i.e. universal).
Bast co-authored "MDA
Explained: The Model Driven Architecture: Practice and Promise" (see Ref.
in slide 18) along with Warmer and Kleppe, who pioneered OCL at IBM and wrote
the introductory book (AWL 1999): "The Object Constraint Language: Precise
Modeling with UML".
This connection is no accident: "MDA Explained" develops a simple
case study ("Rosa's Breakfast Service") using OCL to explain the
declarative or formal specification part of the MDA vision. Compuware's
OptimalJ product is one such solution. OptimalJ is also heavily influenced by
OCL. Wim Bast is Chief Architect of this tool.
This free trial version of OptimalJ includes the Rosa example: OptimalJ free download
Bast and Compuware also presented at OMG's fall 2003 Boston meeting. More details on OptimaJ and the Rosa Breakfast design example are contained in my laptop at: OMGBostonCompuwareExample03-09-03.doc
An extended presentation of the model-to-code transformation approach behind OptimalJ is contained in their Boston Plenary presentation on my laptop at OMGBostonCompuwarePlenary03-09-02r1.ppt (78 slides).
Do not confuse OCL with OLC (Shlaer and Mellor's Object Life Cycles). The latter is about dynamic behavior with control flow or sequencing expressed in state machine diagrams. OCL and OLC can fit together quite compatibly IMHO. Merging them is justified by (my summary of) Bertrand Meyer's Design By Contract philosophy, from Chapter 11 of his book: "Object-Oriented Software Construction" (2ndEd, P-H 1997).
