从四个类比看如何建立高质量、易维护的用例(UseCase)模型

Four Analogies:How to Produce High Quality,Easy Maintained Use Case Model

用例模型在软件开发中占有重要的地位。类和用例都属于类元范畴,具有可比性。该文通过4个类比,由一般较熟悉的,应用于低粒度类设计中的技术、方法和原则过渡到应用于高粒度用例建模的技术、方法和原则,并进一步结合它们给出了用例建模过程的一般步骤。

Use Case Model is very important in the process of software development.Class and use case are classifiers,which make them comparable.For this reason,by four analogies,from the view of techniques,methods and principles applied to the design of low-granularity class,this paper helps us understand more about those applied to the process of constructing high-granularity Use Case model.Further more,based on these techniques,methods and principles,this paper summarizes the general process to build a use case model.
