在讨论建立企业数据仓库基本策略的基础上 ,从主题域的选择、数据粒度层次的划分和多维数据库几个方面深入探讨了基于电信业务的数据仓库系统设计问题 .从数据集市开始 ,由小而大 ,由易至难 ,逐步扩充与完善 ,最终建成一个企业级的数据仓库 。

On the basis of a discussion of the strategy for building the data warehouse, an in depth study is made of the design of data warehouse based on telecom service and in terms of the selection of the subject field, the division of granularity and hierarchy and the multi dimensional database. Beginning from the datamart, from small to big and from easy to difficult, a data warehouse at the enterprise level will be built. This is a feasible strategy for the development of a data warehouse for China's telecom service enterprises.
