CASE: reliability engineering for information systems

Abstract
Classical and formal methods of information and software systems development are reviewed. The use of computer-aided software engineering (CASE) is discussed. These automated environments and tools make it practical and economical to use formal system-development methods. Their features, tools, and adaptability are discussed. The opportunities that CASE environments provide to use analysis techniques to assess the reliability of information systems before they are implemented and to audit a completed system against its design and maintain the system description as accurate documentation are examined.
