Abstract

Component-based software design is still an open issue in Component-Based Software Engineering due to nondeterministic granularity of the externally-provided components. The separation-of-concern development pattern adopted by component-based development (CBD) has prevented its widespread success in practices. Both the developer of a component and the developer of a system using components often face the problem that information vital for certain development tasks is not available, which has various consequences to complicate each stage of CBD process. In order to improve that, service and dynamic service specification are first defined from component's point of view respectively. Then, based on these definitions, a framework for component-based flexible design is proposed in this paper under considerations of domain-specific knowledge and analysis of existing systems. It can help software developers not only understand user's requirements more correctly but also reuse successful development and test cases from domain-specific knowledge and existing systems, which can shorten the lifecycle of CBD.

基于构件的软件柔性设计框架

由于外部提供的组件粒度不确定，基于组件的软件设计在基于组件的软件工程中仍然是一个悬而未决的问题。基于组件的开发(CBD)所采用的关注点分离开发模式阻碍了其在实践中的广泛成功。组件的开发人员和使用组件的系统的开发人员经常面临的问题是，某些开发任务的关键信息是不可用的，这有各种各样的后果，使CBD过程的每个阶段复杂化。为了改进这一点，首先从组件的角度分别定义了服务和动态服务规范。然后，在这些定义的基础上，结合特定领域知识和对现有系统的分析，提出了基于组件的柔性设计框架。它不仅可以帮助软件开发人员更准确地理解用户的需求，而且可以从特定领域的知识和现有系统中重用成功的开发和测试用例，从而缩短CBD的生命周期。
