IDEF4, or ''Integrated DEFinition for Object-Oriented Design'', is an object-oriented design modeling language for the design of component-based client/server systems. It has been designed to support smooth transition from the application domain and requirements analysis models to the design and to actual source code generation. It specifies design objects with sufficient detail to enable source code generation.〔Richard J. Mayer et al. (1995). ('' IDEF4 Object-Oriented Design Method Report '' ) Version 2.0. Jan 1995.〕 This method is part of the IDEF family of modeling languages in the field of systems and software engineering. == Overview == IDEF4 method is a graphically oriented methodology for the design of object-oriented software systems. The object-oriented programming paradigm provides the developer with an abstract view of his program as composed of a set of state maintaining objects which define the behavior of the program by the protocol of their interactions. An object consists of a set of local state defining attributes and a set of methods (procedures) that define the behavior of that particular object and its relationship to the other objects that make up the system.〔Patricia Griffith Friel and Thomas M. Blinn (1989). ("Automated IDEF3 and IDEF4 Systems Design Specification Document" ). Technical report. NASA Johnson Space Center.〕 The IDEF4 method multi-dimensional approach to object-oriented software system design consists of the following items:〔 * Design layers (system-level, application-level, and low-level design), * Artifact design status (application domain, in transition, software domain), * Design models (static, dynamic, and behavior) and the design rationale component, and * Design features ranging from general to specific enabling deferred decision making. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「IDEF4」の詳細全文を読む スポンサード リンク
