Research on the design of large data storage structure of database based on Data Mining

With the continuous development of China's social economy, the informationization function of power grid companies is becoming increasingly powerful, and its effectiveness is very remarkable. However, in the related business of power system, the performance of database cannot be guaranteed. In the process of power marketing, a large amount of data will be generated. In the process of processing a large amount of data, it is necessary to constantly optimize the database to improve the structure of the database. Data mining is a promising subject frontier of database system and new database application. In this paper, a large data storage structure of database based on data mining is designed. The ETL tool in signaling data warehouse is used to realize the integrated design of signaling data storage and application.
