支持渐变过程的软件产品线框架的研究

产品线工程是一种正在出现的软件工程范型,用于开发相同领域的类似产品.在介绍了产品线框架相关的概念之后,根据产品线生命周期的特点,提出了框架从低级框架渐变为高级框架的过程,并在此基础上描述了框架元模型;为了支持从这种渐变,在组件库的基础上建立了视图机制,即原始映射视图、频繁组件项集视图和组件关联视图.这种基于组件库的视图机制,可以指导用户在框架实例化中的组件选取决策,促进了框架的成熟,提高了组件库的复用性能.

Research on Framework of Software Product Line Based on the View Mechanism of Component Repository

Product line engineering (PLE) is an emerging software engineering paradigm for developing similar products in the same domain. After introducing the concept of PLE framework, according to the characteristic of PLE life cycle, we present a process that shades from low level framework into high level framework, and describe the framework meta-model of PLE. In order to support this process, we construct three view mechanisms based on the component library, which are the original-mapping view, the frequent-component-item-set view and the component-relation view. These view mechanisms can guide developer to choose appropriate components in the component library during the process of the framework instantiation. It makes the product line framework matured, and the reusability of the component library increased.
