Currently, software systems must be appropriately developed to support an amount of variability for accommodating different requirements. To such development, a diversity tools has already been designed management (i.e., identification, modeling, evaluation, and realization). However, due this diversity, there is lack consensus on what in fact are even functionalities they should provide. Besid...

Essentially all current software engineering tools share a common technological approach: They use a shallow representation of software objects and manipulate this representation using procedural methods. This approach has the benefit that it allows one to get off to a fast start and quickly provide a tool that delivers benefits. In addition, software engineering tools can undoubtedly be extend...
