This paper presents the solution of energy measuring real-time data based on C/S structure, elaborates the methods, steps and modeling technology of creating date warehouse in the energy measuring real-time monitoring system, and designs the basic frame of the energy data warehouse analysis system, the energy measuring real-time data is updated into enterprise energy measuring real-time data warehouse through the tools of ETL, and thus the prediction efficiency and precision of enterprise energy measurement have been greatly improved. It also provides the basis of decision-making for the enterprise.
