ABSTRACT
This seminar describes the architecture for Web Services from the point of view of components, interactions and application development patterns. It is a framework for the building and deployment of Web Services applications.
Web Services allow applications to be integrated more rapidly, easily and less expensively than ever before. Integration occurs at a higher level in the protocol stack, based on messages entered more on service semantics and less on network protocol semantics, thus enabling loose integration of business functions. These characteristics are ideal for connecting business functions across the Web both between enterprises and within enterprises. They provide a unifying programming model so that application integration inside and outside the enterprise can be done with a common approach, leveraging a common infrastructure. The integration and application of Web Services can be done in an incremental manner, using existing languages and platforms and by adopting existing legacy applications. Moreover, Web Services compliment Java??2 Platform, Enterprise Edition (J2EE), Common Object Request Broker Architecture (CORBA) and other standards for integration with more tightly coupled distributed and nondistributed applications. Web Services are a technology for deploying and providing access to business functions over the Web; J2EE, CORBA and other standards are technologies for implementing Web Services.
