Mass file data storing and reading method

Abstract

The invention discloses a large-batch file data access method, which comprises: merging data of all the small files into a large file; establishing one-to-one corresponding relation between a file name and a file number of each small file; and establishing a corresponding relation between each file number and file information of the small file, wherein the file information comprises the position of the small file in the large file. Correspondingly, the invention also discloses a large-batch file data read method, which is used for reading file data accessed according to the access method. The method comprises the following steps: acquiring the file number of the small file according to the file name of the small file; acquiring the file information of the small file according to the file number; acquiring the position of the small file in the large file according to the file information; and realizing read of data of the small file through an IO interface of the large file according to the position of the small file in the large file. The technical proposal of the invention can save system resources.

Description

technical field [0001] The invention relates to the field of software technology, in particular to a method for storing and reading large batches of file data. Background technique [0002] With the popularization and application of computers, more and more file data need to be accessed. The file data generally refers to all data files that can be stored on the computer hard disk. The access refers to saving the data in the computer memory to the file and reading the data on the file to the computer memory. The access of a small amount of file data has little impact on system resources, but the way of accessing a large number of data files directly affects the utilization of system resources. The quantity of the large batch index exceeds 10 or more. [0003] Such as figure 1 As shown, generally speaking, for the access of large batches of file data, the large batches of file data are usually stored on the hard disk of the computer, and then a file IO (InputOutput, input ...

AI Technical Summary

Problems solved by technology

[0005] First of all, if the application system wants to access a certain file, it needs to create a new file IO interface for the file, which will waste a lot of time on the creation and destruction of the IO interface and waste a lot of system resources;

[0006] Secondly, the scattered files on the hard disk are not conducive to the security of the application system, because these scattered files may be deleted or modified by mistake, which will cause the application system to run incorrectly;

[0007] Furthermore, the scattered files on the hard disk are not conducive to the portability of the application system, because after transplanting the system to other machines, all corresponding data files need to be transplanted there, and there may be missing copies, resulting in application system error
