(ROSE) Reverse engineering legacy code

[Jo Crew]

For reasons that are not important to the question, our project has created a Use Case model and has received code to match the model.  The client part of our system is written in Delphi and the server part in Java – both of these have been reverse engineered into Rose to give Class models – 365 components on the server side and over 1500 on the client side to give some idea of scale.  Our task now is to fill the gap between the static Class model and the Use Case model that we’ve created with some dynamic models.  Obviously this will be labor and time intensive – agreement has been reached to ‘freeze’ the code in order for this effort to take place.   Has anyone ever tried to do this?  Anyone have any advice on an approach?  Recommendations?  Papers (I’ve read the Rational Edge article)?  I’d appreciate hearing any input that might be relevant.     Jo Crew SPS Inc Phone: 703 797 7800
