AN EXTENSIBLE NETWORK QUERY UNIFICATION SYSTEM FOR BIOLOGICAL DATABASES

Database federation enables biological researchers to utilize resource s move effectively, creating an environment in which the researcher ca n query multiple data sources without spending time learning new query mechanisms or issuing redundant queries which need to be integrated. Several mechanisms exist to federate databases. The ENQ Uire system is a network database federation system which uses a World-Wide-Web (WWW ) interface to connect the users to various databases. Generic queries entered via a query generator form are sent in parallel to multiple d atabases, and the results ave presented to the user in a unified forma t. All forms building, query generation, and results translation is do ne on the fly, and individual database translation modules can be adde d dynamically. ENQ Uire is a flexible answer to the problems of databa se federation on the WWW.
