一种从用例模型到分析模型的设计方法

摘要

由于分析模型的复杂性,软件设计师在软件建模过程中往往容易忽略它,直接从用例模型到设计模型,但这样方法难以验证用例的准确性.本文提出了一种从用例模型到分析模型的设计方法,并阐述了这种方法的机理,详细说明了从用例模型中识别分析类的方法,深入探讨了从用例模型中获取实体类的属性及设计分析类的职责.%Software designers usually overlook Analysis Model Because of its complexity, and make Design Model directly from Use Case Model. But this method cannot verify the accuracy of the use cases. This paper presents a modeling method of firstly from Use Case Model to Analysis Model, then mapping Analysis Model to Design Model, and describes the principle of this method, explains specifically how to distinguish Analysis Class from Use Case Model, and discusses deeply how to obtain the attributes of Entity Class and how to design the operations of Analysis Class.
