Abstract

The present invention discloses a data storage method and apparatus. The method comprises: dividing a preset storage device into a first storage region and a second storage region, wherein the first storage region is used for storing an index of a data file, and the second storage region is used for storing the data file and the data file is to-be-stored data stored in the form of a file; dividing the second storage region into N storage spaces, wherein N is a positive integer and each storage space has a same storage capacity; and storing the to-be-stored data into the N storage spaces in a sequential order in which the to-be-stored data are generated. According to the technical scheme provided by the present invention, a simple and easy mass data storage method is achieved and data searching efficiency can be effectively improved.

Description

technical field [0001] The present invention relates to the field of data storage, in particular to a data storage method and device. Background technique [0002] At present, the existing search methods for realizing large-capacity data are usually based on databases or relatively complex algorithms, which occupy a large amount of FLASH and memory resources during implementation, and are not suitable for resource-limited environments such as single-chip microcomputers. [0003] The search methods for large-capacity data commonly used in related technologies mainly include the following four types: [0004] Solution 1, a multi-level bucket hash index method for massive data retrieval, which mainly includes: (1) providing a bucket mapping table to reduce the space occupied by the hash index file on the disk; (2) the hash index uses Multi-level buckets are established, the size of the disk block is an integer multiple of the sector size, each disk block has one or more basic ...
