Abstract: A number of work stations are configured as clients in a client-server environment. The clients enter requests that must be validated and approved prior to loading into mainframe databases. This occurs by staging. The server connected to the various workstation clients is a mid-range server that cooperates with a mid-range database. The mid-range database allows the mid-range server to check incoming requests against other requests being processed by the system. If the request does not repeat or conflict with a request undergoing processing by the system, as noted by the mid-range database, the request is transferred to a staging database, connected to a universal server. The universal server accesses the mainframe databases to perform more precise checks of the request. If validated, the request is entered into a mainframe database and the mid-range database is updated accordingly.
