Query Manager

The query manager is the glue that binds the application to the remote agent. It is part of the application. It performs the following functions:

• Calls agent and obtains results
• Handles requests in parallel or spools query requests
• Activates and populates appropriate forms upon receipt of data

Although a query manager is not required, it allows simpler coding and more features. A key feature should be the ability to resume an application. Other features are:

• Cleans up obsolete MDBs
• Reports failures and time-outs
• Retrieves data from cache (old MDB) instead of submitting new queries
