基于元数据的数据仓库并行方法的应用研究

Research on the Application of Parallel Method in Data Warehouse Based on Metadata

提出一种并行转换元数据管理的软件体系结构,结构基于公共仓库元模型(CWM)规范,以CWM元模型规定元数据集成、交换内容,XML元数据交换提供实时元数据交换和共享机制,采用并行数据转换结构PDTS,即可实现对应分布元数据的动态读取。体系结构有效实现了对元数据互操作和实时分布存取的可行性和有效性。

Proposes a software architecture for Parallel data transfer structure, the architecture is based on common warehouse metamodel （CWM） specification. CWM metamodel identifies the structure and semantics of integrating and exchanging, while XML metadata interchange （XMI） provides real-time metadata exchanges and shared mechanism, and the parallel data transfer structure is needed to correspond to accessing dynamically metadata of distributed software component. The architecture shows the feasibility and validity of the metadata interoperability and distribution of real-time access.
