description The embodiment of the invention discloses a data storage method and device, and relates to the technical field of computers. The method comprises the steps that various pieces of data to be stored toa database are acquired, wherein each piece of data comprises a numeric value corresponding to a preset column name of the data base; at least one data column is determined from the various pieces ofdata, at least one data column file is generated, and one data column in the at least one data column is stored in each data column file; bitmap index files of the various data column files are generated; and the various data column files, the various bitmap index files and a target corresponding relation are stored, wherein the target corresponding relation is the corresponding relation among thedata column files, the bitmap index files of the data column files and preset column names corresponding to the data columns stored in the data column files. By applying the scheme to store the data,high concurrency access on
