Service Oriented Architecture Based Electric Power Real-time Data Ware House

Currently traditional data warehouse is no longer satisfying the electric power enterprises decision making support, the real time data ware house can support the electric power enterprise in daily tactical operation support, and the real time data ware house implementation method, can make feasible real time data ware house architecture based on Service oriented architecture. This service oriented architecture based real time data ware house architecture uses the web service to pack the various source electric power data base systems, and the various changed data was captured by the data capture web service. When it comes to the data transformation and flow, the update strategy based on message queue and XML are used for the real time updating. Also, the multi level real time data cache is used for real time data storage. Using this real time data ware house architecture, we can implement the electric power real time data ware house easily.
