A general term for tools which automate various of the software engineering life cycle phases. Essential model: A software engineering model which describes the behavior of a proposed software system independent of implementation aspects. Implementation model: A software engineering model which describes the technical aspects of a proposed system within a particular implementation environment. Information model: A software engineering model which describes an application domain as a collection of bjects and relationships between those objects Module structure chart: A component of the implementation model; it describes the architecture of a single computer program. Object: An"entity or" thing"within the application domain of a proposed software system Object collaboration model: A component of the essential model; it describes how objects exchange messages in order to perform the work specified for a proposed system. e 2000 by CRC Press LLC© 2000 by CRC Press LLC Defining Terms CASE: Computer-aided software engineering.
