متن کاملI-Pattern for Gap Analysis
Patterns are an effective way to express solutions to constantly occurring problems in software engineering. Books like Erich Gamma’s Design Patterns ([Gam94]) or Martin Fowler’s Analysis Pattern ([Fow96]) helped to develop a common understanding of problem solving in this field. The pattern catalog developed by members of the chair Software Engineering for Business Information Systems (sebis) ...
