摘要
数据中心基础数据积累通常使用三种手段:1)ETL技术;2)数据联邦技术;3)中间件技术。但三种技术侧重各有不同,不能同时满足数据集成的持久性与可用性。结合技术优势提出数据虚拟整合,为解决数据虚拟异构数据模型间的数据转换问题,通过对数据虚拟的分析,提出了一种基于元数据驱动的数据虚拟系统体系结构。构建了用于描述和存储映射策略的支撑元模型,并建立了相应数据路由策略。提出了对等主键思想,降低了处理阻抗。
Data center underlying data accumulation usually use three kinds of means,which are ETL technology, Data Federation technology, Middleware technology. But the three technology focuses on different, which can＇t satisfy the data integration and persistence of usability at the same time. Combining with technical advantage virtual data integration is put forward. In order to solve the data of heterogeneous data model of data virtual between the conversion of data,according to analyze the data virtual,a kind of data virtual architecture for data transforming is proposed which merges technique of metadata driven. A series of supporting metadata models are built to describe and store ploeies of mapping pattern in details, meanwhile the corresponding data routing strategies are built. For reducing the processing impedance, the equivalence primary key ideas is put forward.
