Un formalisme pour la traçabilité des transformations
When developing software system in industry, system specifications are heavily used in communication among analysts and developers. However, system evolution, employee turn-over and shorter deadlines lead those documents either not to be up-to-date or not to be consistent with the actual system source code. Yet, having up-to-date documents would greatly help analysts and developers and reduce development and maintenance costs. Therefore, we need to keep those documents up-to-date and consistent.  We propose a novel mathematical formalism to describe and manipulate the evolution of these documents. The mathematical formalism is based on Hoare triple to represent the transformations and group theory and groups homomorphisms to manipulate these transformations and apply them on different representations.  We illustrate our formalism using two representation of a same system: PADL, that is an abstract design specification (similar to UML), and JCT, that is an Abstract Syntax Tree for Java. We also define transformations describing their evolutions, and transformations transposition from one representation to another. Finally, we provide an implementation of our illustration, a plugin for the Eclipse IDE detecting source code transformations made by a developer and a source code generator for integrating new representations in the implementation.
