摘要
针对需求分析中的系统需求描述问题,本文提出了一种以资源描述需求的方法,分析了这种方法与传统需求描述方法的异同;实现了对资源及需求的形式化描述,并详细讲述了获取需求的过程;最后给出了需求的存储形式和需求同资源的映射算法。
This article proposes a method of requirement description based on resources to solve the problem of system requirement description in requirement analysis, and tells the difference between the traditional requirement description methods and this method. This paper achieves two formal descriptions of resources and requirements, and shows the de- tailed process of requirement access. Finally, a form of storage for the requirements and an algorithm for the mapping between the requirements and the resources are given.
