Large-scale hot continuous rolling data scheme customizing system based on cloud computing

The invention provides a large-scale hot continuous rolling data theme customizing system based on cloud computing. The large-scale hot continuous rolling data theme customizing system comprises an ETL (electron transport layer) module, a data persistence layer and a theme customizing layer. The ETL module is used for realizing original hot continuous rolling system data analysis, a cloud data warehouse data sheet building and a data extraction; the data persistence layer organizes and stores structuralized data extracted from the ETL module by utilizing the cloud data warehouse; and the theme customizing module, aiming at solving the problem of data theme analysis in the cloud data warehouse, provides users with reasonable customizing schemes through a theme pool and an experience pool, and provides users with a general data analytical function through a public data mining method pool and a MapReduce module container, so that working efficiency of data management staff can be improved. The theme customizing system has flexible expandability, can be integrated in any original hot continuous rolling system data system, can solve a complicated data theme clarifying problem when a user's requirement is unclear, and can provide a reliable data set guarantee to the hot continuous rolling system data analysis.
