摘要
模型驱动的企业集成要求企业模型具有精确的、形式化的、一致的表达,现有研究中多视图企业模型一致性的定义依赖于具体的建模框架,刚性的视图一致性维护方法制约了视图配置的开放性。在分析多视图企业建模框架中模型一致性问题的特点和原因基础上,借用软件工程中元对象机制(MOF)的思想,将产生一致性问题的视图间语义约束元化到元元模型层,并给出了视图的形式化定义。这种视图及一致性定义及维护方法具有通用性和严格性,同时使得建模框架中视图的配置具有良好柔性。
In order to realize the model-driven enterprise integration, enterprise model is required to be precise, formal and consistent. Within related works, the consistency problem of multi-view enterprise model depends on the specific modeling framework, and the rigid maintaining approaches of view consistency restrict the flexibility of viewpoint configuration. Based on the analysis of the characteristics and causes of consistency problems within multi-view enterprise modeling frameworks, with the idea of meta object facility （MOF） within software engineering field, the semantic constraint which causes the viewpoint consistency problem is meta-modeled, and the formal definition of viewpoint is proposed. Such this approach of defining and maintaining the viewpoint consistency has the features of generality and rigority, and makes the configuration of viewpoint flexible.
