Information drives today's businesses and the internet is a powerhouse of information. So data integration gives the user with a unified view of all heterogeneous data sources. The basic service provided by data integration is query processing. But if we are considering a query that involves multiple domains, then we find that general purpose search engines fail to answer such queries and domain specific search services cover only one domain. Hence currently the only solution to this problem is to pose the query separately to dedicated services and feed the result of one as input to another. Our consideration could be drawn from the work in data integration, where two basic approaches has been proposed to specify the mapping between global ontology and a set of services, that are GAV and LAV. This paper presents a model, providing fully automated support to multi domain queries. This model (a) integrates different kind of services into a global ontology (b) covers query formulation aspects over global ontology and query rewriting in terms of local services (c) Several web related services that helps to conquer the problem and the package that we have offered here is XAMPP Control panel.
