主动数据库中交叉数据依赖关系的研究

Study of Inter-data Dependencies in Active Database

针对在ADB中出现的交互数据依赖关系,提出如何在基于语义的ADB模型中保证分布在相关的不同数据库的交互数据依赖关系.参照实例模型对ADB中数据元素之间的匹配和依赖关系进行分类细化,并依据概念级解释器的方法,在实例模型基础上导出依赖图,解决了带有计算性的交互数据依赖关系,使得事件执行的正确性通过依赖关系的加强得到保证.

This paper proposes how to ensure the inter-data dependencies relation of a distributed correlative heterogenous database in an Active Database based semantic. Referring to our case model, the matching and dependencies among the data elements in ADB are classified and refined, and the dependency graph is deduced on the basis of the case model according to the Conceptual Level Translator method. With it, we can resolve the computational inter-data dependencies and enforce the correctness of event.
