ABSTRACT
During the past 10 years, with the advent of the World Wide Web (WWW), the consumer service provider concept has been digitized and enforced via the web. is way, we now have web-supported services where a consumer may request a service via the website of a service provider and the service provider provides the requested service. is service could be making an airline reservation or purchasing a book from the service provider. Such web-supported services have come to be known as web services. An information system that supports service implementation is a service-oriented information system. An architecture that provides support for the implementation of services has come to be known as a service-oriented architecture (SOA).
