Abstract:
An apparatus for designing an information system, said apparatus comprising:an input module for receiving descriptive input of a target information system, said descriptive input including descriptions of business processes and business functions; and a construction module for receiving said descriptive input from said input module, said construction module: (i) deriving quantitative input from said descriptive input, said quantitative input including number and kind of hardware and software components for said target information system; (ii) designing a multi-layer mathematical model of said target information system from said quantitative input, said multi-layer mathematical model designed prior to implementation of said target information system, said layers of said multi-layer model comprising a business layer, an application layer, and a system/network layer; said business layer modeling performance of said business processes and said business functions, said business layer generating data for said application layer and said system/network layer; said application layer, responsive to said generated data, modeling performance of said software components, including modeling performance of said software components presenting service requests to said system/network layer; said system/network layer, responsive to said generated data and said service requests, modeling performance of said hardware components, including modeling performance of said hardware components generating processing and servicing data, said processing and servicing data of said system/network layer factored into said business layer and said application layer; and the modeled performance of said hardware components being factored into the modeled performance of said software components and the modeled performance of said business processes and said business functions, and the modeled performance of said software components being factored into the modeled performance of said business processes and said business functions.
