Method and system for analyzing big data

The invention discloses a method and a system for analyzing big data. In embodiments of the invention, an original data temporary table caching big data and an index table are set in local cache of aserver while the big data is stored in a distributed database in a striping manner according to time. Position information of corresponding big data in the original data temporary table is set in theindex table. In big data analysis, the big data can be called directly from the original data temporary table according to the index table in the server. Since in the big data analysis, a secondary index method is used, an obtained analysis result is stored in an analysis result table of the distributed database, and obtaining the big data in mass big data in the distributed database is not needed, so time consumption is short and the method is easy to implement. Furthermore, the position information of the big data in the original data temporary table is information that a remote procedure calls the big data, and the
