Software Evolution with UML and XML provides a forum where expert insights are presented on the subject of linking three current phenomena: software evolution, UML and XML. Software evolution and reengineering are a real problem in the software industry; various attempts have been made in these areas and there is still room for improvement. Tackling evolution with the help of UML and XML can be very beneficial to the software community, especially as the cost of software evolution makes up a considerable proportion, sometimes even 70-80 per cent, of the total budget of a software system. Software Evolution with UML and XML not only investigates the potential powerful applications of two popularly used languages, UML and XML, in the field of software evolution, but also discovers what will happen when these three are linked to work together.
