37. To provide a generic meta-model for expressing software evolution analyses, we need to recognize evolution as an explicit phenomenon and model it as a first class entity. to Understand Software Evolution Modeling History vorgelegt von Tudor Gîrba von Rumänien Inauguraldissertation der Philosophisch-naturwissenschaftlichen Fakultät der Universität Bern Leiter der Arbeit: Prof. Dr. Stéphane Ducasse Prof. Dr. Oscar Nierstrasz Institut für Informatik und angewandte Mathematik
