Reality to communication field is presented for fully using data warehouse technology to existing data structures become available, controllable, scalable data organization, to adapt to the field of communication at all levels of managers and business analysis.In this paper from the data warehouse requirement analysis includes the participation of members, each member of the role played by; logic model construction through software design, to determine the relationship between tables; 下载后可任意编辑physical model construction process table and detailed audit, used to support the proposed requirement; data warehouse design with ODS, DWD, DWA levels, the horizontally stratified longitudinal domain concept, specific implementation of the establishment, and in late stage provides error emergency measures, data warehouse maintenance and optimization.Keywords： data warehouse, physical model, maintenance and optimization目录第一章 数据仓库概述.............................................................................................................11.1 ...
