基于UML用例图的软件产品线需求建模方法

软件产品线方法是一种面向特定领域的、大规模、大粒度的软件复用技术。明确建模和描述软件产品线需求是软件产品线开发的关键问题之一。而传统的UML用例图等方法不足以完整描述产品线需求，特别是其变化性。通过分析软件产品线开发过程和软件产品线需求建模的特殊性，采用扩展UML用例图标签的方法，实现对软件产品线需求的明确描述。以网络图书销售软件产品线为例，进行具体说明。

UML Use Case Diagram-based Software Product Requirement Modeling Method

Software Product Line is a new software reuse technique,which provides a large- scale and great granularity reuse in a special domain.Modeling and describing the requirements of software product line is key to develop software product line.Traditional methods such as user case are not enough to model requirements of software product line, especially the variability.This paper analyses not only the development process but also the character of requirement modeling in software product line scenario,and provide a method to model definitely requirements of software product line by extended tags of user case.Furthermore it gave many detailed instructions by taking an example,Internet books sale software product line.
