Summary

This book focuses on Service Oriented Architecture (SOA), the basis of sustainable and more agile IT systems that are able to adapt themselves to new trends and manage processes involving a third party. The discussion is based on the public Praxeme method and features a number of examples taken from large SOA projects which were used to rewrite the information systems of an insurance company; as such, decision-makers, creators of IT systems, programmers and computer scientists, as well as those who will use these new developments, will find this a useful resource.
