The Design and Realization of the Universal Report System in the Power System Based on Physical View

As top enterprise in China, Power companies' Information request is very urgent and necessary. But for there is many information system and these system have various systems of different technical background of the period of construction, the problem of information isolated island becomes more and more serious. So a compatible and advanced information platform-universal report, is an urgent affair. This paper discusses a novel and efficient information integration technology aiming at information isolated island, based on Data Warehouse theory and other existing systems. This paper brings two contributions: 1) Resolving the conflicts among isomeric data resources by data maintaining module. 2) Realizing data analysis on the basis of integration through physical views and self-definition sampling strategies.
