Abstract
This paper categorizes and discusses the software, hardware and system lessons learned to date that could significantly enhance large-scale information systems: they include designing for an automated operations-oriented environment; developing a real-time system; building on a hardware-independent operating system, employing a modular software development approach; building on a distributed network of processors; employing a data base management system; developing enhanced applications; considering a dedicated system; and building in a system evaluation component. Additionally, the paper suggests that current data systems should be upgraded to information systems, which, in turn, should be upgraded to knowledge systems.
