Today, reliable software systems are the basis of any business or company. The continuous further development of those systems is the central component in software evolution. It requires a huge amount of time- man power- as well as financial resources. The challenges are size, seniority and heterogeneity of those software systems. Christian Wagner addresses software evolution: the inherent problems and uncertainties in the process. He presents a model-driven method which leads to a synchronization between source code and design. As a result the model layer will be the central part in further evolution and source code becomes a by-product. For the first time a model-driven procedure for maintenance and migration of software systems is described. The procedure is composed of a model-driven reengineering and a model-driven migration phase. The application and effectiveness of the procedure are confirmed with a reference implementation applied to four exemplary systems.

From the book reviews:
This book is well written and well organized. Its main contributions revolve around an in-depth discussion of the theory, terminologies, and methodology behind model-driven software migration, the practicality of the approach using a complex legacy system, and validation of the work. It can be used as a textbook or reference by graduate students and professionals who are interested in advanced topics in software maintenance. (Hassan Reza, Computing Reviews, August, 2014)
