By allowing us to replace or alter legacy systems in real time, Service-Based Architectures (SBA)transform traditional Enterprise Application Integration (EAI) efforts to the next level. This book reveals to IT professionals how SBA adds flexibility for expansion and upgrades while solving longstanding problems with current enterprise architectures. Using Abate's pioneering implementation at a major Fortune 500 fashion corporation as a giant real-world example, the authors explain how to build the SBA from the ground up. They give comprehensive coverage to combining multiple industry standards and technologies such as Java 2 Enterprise Edition (J2EE), CORBA, Enterprise JavaBeans (EJB), and XML to integrate systems with Web front-end applications. The benefits of SBA in data warehousing, interoperability, access points, and real-time connectivity as well as SBA project management are also covered.
