Heterogeneous database integration method of electric power enterprise based on XML

Since the conventional integration methods cannot distinguish the useful data when there is much heterogeneous data with the same semantic, the data integration time is long and the utilization rate of power resources is low. Based on this, an XML-based heterogeneous database integration method for electric power enterprises is designed. Firstly, the same semantic objects of heterogeneous databases are identified to reflect the integration conflicts of the same semantics of heterogeneous data in power enterprises, and then the integration framework of heterogeneous data exchange in power enterprises is constructed by using XML, and finally the similarity value of numerical attribute data in power enterprises is refined. Thus, the efficient integration of heterogeneous databases in power enterprise is realized. The experimental results show that the proposed method has a relatively high utilization rate of heterogeneous data resources in power enterprises, all above 98%, and its integration time is short, less than 4s, which is better than the comparison method. The proposed method can help power enterprises to quickly manage complex business data and improve their automation and informatization levels.
