ABSTRACT:
To provide data to a user front end while conserving processor resources and network bandwidth, a front end driver operates between the user front end and data processing and storage devices. When users access databases from the user front end, the front end driver maintains virtual objects containing control information associated with the windows and data items visible at the user front end. The user front end need only maintain data corresponding to the visible data items, while the front end driver provides updated versions of the visible data items to the user front end. The updated data items may be provided at refresh intervals, independent of the rate at which the front end driver downloads data from the storage devices. Thus, the system provides access to all database data in a manner that appears to the user as real time, while conserving resources at the user front end.
