M.Prabhavathy, K.Sivasankari

In current business scenario, most of the software is offered as services which are exposed using contracts by the service providers. The client or user pays the service provider for the duration of usage. In process of business intelligence data integration is inevitable. Data federation is a form of data integration which is implemented as a servicer. The federated query service gets the input query, decomposes into sub queries, post the sub queries to different data sources, extract the required data from sources and integrate into a single virtual view. This paper proposes the algorithms for federated query processing service and uses distributed XML database for data federation. The experimental results are provided
