SOA and Web Services Interface Design

With the introduction of increasingly complex Web services over the last decade, there has been an explosion of interest in service-oriented architecture (SOA), a structural style whose goal is to achieve a coupling of interacting services - functionalities such as filling out an online application for an account, viewing an online bank statement, or placing an online booking or airline ticket order. These services operate through specific interfaces that control and define their operation. However, due to the evolving nature of enterprises, new services and applications must often be incorporated into these same interfaces. Such incorporation can be costly and complex if the original interface is inflexible or incompatible with the technology utilized by the new applications. In his new book, data architecture guru James Bean teaches you exactly how to design web service interfaces that are capable of being extended to accommodate changing business needs and promote incorporation simplicity. The book first provides an overview of critical SOA service design principles and then offers explicit, real-world techniques for ensuring compliance with these principles. Using a focused, tutorial-based approach the book provides working syntactical examples - described by Web services standards such as XML, XML Schemas, WSDL and SOAP - that can be used to directly implement interface design procedures, thus allowing you immediately generate value from their efforts.
