Overseas Data Warehouse Qwmdmp Data Management Platform To Design And Build,

The paper firstly introduce the fundamental theory of data warehouse and the management of metadata. Then it presents a model of metadata management platform according the characteristic of qiaowu data warehouse and metadata management. In general,this paper can be divided into two parts: the research of data warehouse and metadata management, the particular application ?implementation of QWMDMP metadata management platform.About data warehouse , this paper mainly introduced the conception, system architecture and data structure. According these knowledge, we have a clear understand of data warehouse. Following , we introduced the important effection of metadata in data warehouse, the classify of metadata and the development direction of metadata management and brings forwards the method of realizing enterprise metadata management.At last , this paper presents the design and implemention of a J2EE-based QWMDMP metadata mangement platform according the characteristic of qiaowu data warehouse and metadata mangement. We firstly introduced the sytem structure and function module, then give the mainly characteristic of system as follow:(1) Excellent expansibility in client tier.(2) Platform- independent system(3) Xml is the core of system and the standard of transfer data.(4) Excellent universalness.This paper analysis every layer of system structure based on J2EE three tier model.This included the application client and web client in client tier, the design of EJB in middle tier and the design of metadata database in data tier.The implemention of QWMDMP metdata mangement platform is satisfied with the requirement of qiaowu data warehouse and presents some ideas to designing of the Data Warehouse.
