Problems solved by technology

[0003] When reading and writing file data, it is necessary to frequently call functional interfaces such as file reading and writing positioning, index query, data encryption and decryption, and switch between user mode and kernel mode. A read and write process takes a lot of extra time, thus prolonging the time required for file system processing and reducing the management efficiency of the media file system

Abstract

The invention discloses a method and device for managing data, and relates to the technical field of electronic information. The method and the device are used for improving management efficiency of media file systems. The method includes the steps of obtaining the data to be processed through a system calling interface, distributing a system node record (SNRec) on the SMU and a media node record (MNRec) on the MMU to the data to be processed, establishing the mapping relation between the SNRec on the SMU and the MNRec on the MMU, establishing the mapping relations between the MNRec on the MMU and data blocks (DB) on the DMU, and storing the data to be processed to the corresponding DB corresponding to the MNRec on the MMU. The method and the device are suitable for services such as storing, sharing, distributing and playing of media files.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method and device for managing data. Background technique [0002] At present, technologies such as storage, sharing, distribution, and playback of file data are widely used. File data is mainly processed through the file system, such as NTFS (New Technology File System, new technology file system) and EXT4 (The fourth extended file system, the fourth extended log file system). When this type of system processes file data, It is necessary to perform processes such as encryption and decryption, data stream reading and writing, and indexing, which requires frequent reading and writing of file data. [0003] When reading and writing file data, it is necessary to frequently call functional interfaces such as file reading and writing positioning, index query, data encryption and decryption, and switch between user mode and kernel mode. A large amount of additional t...
