Abstract: An apparatus for and method of utilizing an Internet terminal coupled to the world wide web to interface with an existing proprietary data base management system by building a component which accesses said proprietary data base management system. A central process provides a listing of tables or steps to a use at the Internet terminal. The user selects an ordered subset of the list which defines the desired component. The component design is stored as this ordered subset. The design may be subsequently converted to script, as convenient, for run-time execution.
