6. 6 Retrieving information from official sources Finding information and searching in many sources are time consuming. Finding related information from multiple sources sometimes infeasible. In certain cases, client side users have to discover for needed information.

7. VR is designed to find and discover related information from multiple information systems. VR aims to provide integrated interfaces for retrieving data from different sources. 7 Retrieving information from multiple sources ADAST
