"Web Services have emerged as a powerful tool for building complex but adaptive and agile enterprise systems in heterogeneous environments, enabling effective inter- and intra-enterprise integration. Perspective on Web Services: Applying SOAP, WSDL, and UDDI to Real-World Projects by Olaf Zimmermann, Mark R. Tomlinson, and Stefan Peuser contains erverything you need to know about developing and deploying Web services-oriented enterprise applications. Whatever your role in a Web Services application project - for example, software architect, developer, project manager, or systems administrator - you will find useful information in this book. (...) The authors combine their practical experience in Web service-oriented enterprise applications with reviews and a hands-on examination of the latest Web service specifications and technologies and IBM product capabilities."Dragan Stojanovic on dsonline.computer.org
