Abstract

The invention provides a method for storing data. The data to be stored include original data identifiers, and original data contents corresponding to the original data identifiers. The method comprises the steps of clustering the data to be stored according to the original data identifier, wherein each class is corresponding to a data block; generating data block identifiers according to the original data identifiers of the store to be stored and corresponding to the data blocks; compressing the original data contents of the data to be stored and corresponding to the data blocks; storing the compressed data contents into data areas of the data blocks and acquiring address identifiers of the compressed data contents; generating indexes according to the original data identifiers of the data to be stored and corresponding to the data blocks and the address identifiers; storing the indexes into index areas in the data blocks. With the adoption of the data storing module, the use efficiency of the data is greatly increased. The invention further provides a data storing device, a data querying method and a data querying device.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data storage and query method and device. Background technique [0002] With the advancement of computer technology, computer technology has had a great impact on people's life and work, and a large amount of data needs to be stored and processed by computers. At present, the data to be stored by computers has risen from the original MB (megabytes) and GB (gigabytes) to TB (terabytes) or even PB (petabytes). With the explosive growth of data, how to reduce the cost of data storage has become an urgent problem to be solved. [0003] The traditional means of reducing data storage costs is to directly compress the data and store it. However, this way of sacrificing computing time in exchange for local storage space reduces the efficiency of data usage. For example, when querying data, the compressed All data can only be used after decompression. Contents of the invention ...
