分布式通信网络管理数据仓库的构建

通信网络管理系统中积累了大量的操作型网络管理信息数据，这为数据仓库的应用创造了良好的条件。同时，为了对各级通信网络管理中心分别提供不同层次的管理决策支持，建立和维护一个分布式数据仓库环境显得非常必要。根据通信网络管理的特点和实际需求，设计了一个3级分布式通信网络管理数据仓库的结构模型，并对该模型进行了数据划分，最后研究确定了一个“自底向上”的开发策略。

Construction of distributed data warehouse for communications network management

A large amount of operational data accumulates in communications network management system, which provides a good condition for using data warehouse technology, At the same time, in order to provide different management decision support for individual level of communications network management centers, it is very necessary to establish and maintain a data warehouse. Based on the characteristics and actual requirements of communications network management, a structure model of three levels distributed data warehouse for communications network management is designed. Then this model's data is divided. Finally a "bottom to top" construction maneuver is studied and confirmed.
