Design and development of SOA for information retrieval using web services

With the growing amount of information in various domains, retrieval and analysis is the mostfrequently used operation. Various institutions/organizations generate valuable information in variousdomains which is queried and analyzed by users for various purposes. Most of the applications performingthese tasks are predominantly database driven and tightly coupled with the system. This limits thepossibilities of seamless database integration with other sources of knowledge and also their ability toadopt to changes in the information structures. We describe a generic approach comprising a looselycoupled system with an ability to perform complex querying, analysis and seamless integration with othersystems, both off line and over Internet.
