| 特定领域软件体系结构(domain-specific software architecture,简称DSSA)是特定领域开发中的重要资产,而基于特征的领域模型使得从领域需求到DSSA的映射成为可能.引入本体作为特征模型的描述基础,通过该方法得到的领域特征本体将同时作为领域内业务构件的语义描述基础存在.在此基础上,提出了基于特征模型和构件语义的概念体系结构设计方法.该方法综合考虑了特征模型中的共性、可变性、绑定时间以及结构关系、依赖关系等对DSSA设计的影响,同时以构件语义作为特征到概念构件设计的过渡.相关方法已经实现为基于本体的特征建模工具和基于特征模型的体系结构设计工具,为特征驱动的领域开发提供了有力的支持. |

| Abstract: |
| DSSA (domain-specific software architecture) is essential for the development of applications in the same domain. Feature-based domain model makes the mapping from domain requirements to DSSA possible. In this paper, ontology is introduced as the representation basis for feature models, and feature ontology of a domain is also taken as the semantic description basis for business components in the domain. Then a feature model and component semantics based method for conceptual architecture design are proposed. Commonality, variability, binding time, structural relations, and dependencies are taken into account in the method. The component semantics act as the transition from feature to conceptual component design. The methods have been implemented in the ontology-based feature modeling tool and feature-based architecture development tool, and exhibit effective supports for domain development. |
