| 摘 要： | 为了解决异构数据源融合和数据仓库的迁移问题,结合数据仓库和构件技术的思想,提出了一种基于数据仓库的通用OLAP(online analysis process)数据接入构件的设计方案.该方案针对完成数据操作封装的数据接入构件进行了建模,并且针对这种模型设计了一个基于构件的OLAP通用数据接入原型系统,实现了OLAP界面展示工具和异构数据源的自由配对和无缝迁移.

| Abstract: | In order to deal with the urgent problems,such as the convergence for heterogeneous databases and transfer of data warehouse,a general OLAP data access component was proposed based on data warehouse and the concept of data warehouse and component technology.Firstly,a design model of data access layer which encapsulated the data operations was presented.Then,a general OLAP data access layer prototype system was established based on components in accordance with the model referred above,which made the OLAP di... |
