基于POSC平台的数据仓库

Data warehouse based on POSC sip

介绍了按照POSC软件集成平台技术进行数据集成、建立数据仓库的方法 ;数据仓库的总体结构是以POSC数据平台为基础 ,并基于Epicentre的多维数据结构 ;数据集成是从源数据库中抽取数据 ,根据映射关系 ,自动把数据调整并加载到POSC数据仓中 ;采用 4层结构的元数据模型 ,实现了可扩充性强的资源管理 ;

This paper introduces an approach to integrate data and build data warehouse according to POSC SIP.In the framework of the data warehouse, POSC data platform is used as basic layer which is based on Epicentre multi\|dimension data structure. Data integration means retrieving data from source and converting and loading into POSC data store on mapping rules. Four\|layer metamodel architecture is created, and extendable source explorer is implemented. Data market is built on topic and multi\|strategy data mining means are presented.
