需求单元链接管理的一种新方法

在研发处理较小需求单元的需求管理工具过程中,研发人员面临着如何管理这些单元之间链接的难题。本文首先说明了若干个需求单元及其链接将会构成一个有向图;然后,为了管理这些链接,在介绍了直接操纵数据库法、关联矩阵法、三元组表法等三种方法的基础上,本文提出并实现了把链接作为需求单元属性的新方法;随后详细分析了这四种方法的优缺点;最后讨论了链接使用的方式。经实验证明,新方法和直接操纵数据库法两者的速度差别在105 以上。

New Method for Requirement Unit Link Management

How to manage the links between smaller requirement units is a difficult problem in the course of new requirement management tool development. This paper explains that the requirement units with their links compose a directed graph. After introducing three management methods: to manipulate database directly, to use incidence matrix and to use list of three-tuples, this paper brings forward and develops a new method: use links as the attributes of the requirement units. Then, this paper analyses the advantage and disadvantage of the four methods in detail. Finally, this paper discusses the mode of the link usage. Experiment indicates that the speed of the new method is 10~5 times than the one of manipulating database directly.
