Abstract: A multi-desktop computer system for a bank or other financial institution includes a plurality of functional desktop routines, each desktop operating on an identical "platform" of object-oriented routines. This "platform" of common object-oriented routines for use by each of the desktops, substantially reduces the design requirements of the desktops in that they only have to be designed to conform to the command structures of the object-oriented routines, and they do not have to be designed to any specific mainframe message structure or protocol. All of the functional desktops may be compiled together, along with the "platform" of object-oriented routines, to form one integral program, where a particular desktop will be activated, depending upon its need. The system enables a user to move between desktops, depending upon the need to activate a particular desktop. The system includes a system database that allows the desktops to share information with one another, such as customer information.
