摘要：A system for efficiently retrieving information from one of several databases.The system acts as an intermediary between users and databases, managing user access
to the databases so that query specification, query execution, and query result retrievalcan occur efficiently and securely. After verifying the identity of a user, the systemdetermines the databases which the user is authorized to access and the databasequeries which the user is authorized to execute. The system then presents the user withavailable queries. If the user selects a predefined report form, the system presents theuser with previously used options for that report form which the user can select. If theuser selects a type of inquiry, the system presents the user with previously used inquiriesof the selected type. After the user finishes specifying the query to be executed, thesystem then allows the user to schedule the query execution. When the scheduledexecution time arrives, the system determines whether the selected query can becurrently executed, and whether it is actually necessary to execute the query to returnaccurate query results. If execution is needed to obtain accurate query results and theselected query can be currently executed, the system automatically performs the queryexecution. After query execution is completed, the system notifies specified users of thequery results, and ensures that the query results will be available to the requesting userand to other users.
