Multi-Dimensional Data Analytical System Oriented the Vacuum of the Condenser
Xiong Zhang · Thermal Turbine · 2006
Related concepts of multi-dimensional data model, data cubes and OLAP(Online analytical process) are presented,and a clustering method for establishing the dimension of multi-dimensional model is also provided,which can be used to define the dimension for the use of OLAP on the historical data of condenser system.With the vacuum variation of the condenser as an object,data cubes are created based on the multi-dimensional model of the condenser system.Information from huge historical data using OLAP is introduced.The advantages of OLAP vs traditional data analytical method have been showed in this paper.
