Abstract:

This article proposes a method of requirement description based on resources to solve the problem of system requirement description in requirement ana lysis, 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   the mapping between the requirements and the resources are given.

Key words: requirement description, requirement storage, resource description, mapping algorithm
