Problems solved by technology

[0004] Moreover, when the user requests the audio and video application to delete the historical audio and video behavior data, the audio and video server will directly delete the historical audio and video behavior data from the database. In this case, the user cannot request the audio and video application to retrieve the deleted history Audio and video behavior data

Embodiment

[0035] figure 1 It is a schematic structural diagram of an audio-video system in the prior art provided by an embodiment of the present application. Such as figure 1 The audio-video system in the prior art shown generally consists of a terminal, an audio-video server and a database. Users can install a client (audio-video application) on the terminal, and the audio-video server is used to provide technical support for the audio-video application.

[0036] Database (Database), in short, can be regarded as an electronic file cabinet - a place where electronic files are stored. Users can add, query, update, delete and other operations on the data in the files. The so-called "database" is a collection of data that is stored together in a certain way, can be shared with multiple users, has as little redundancy as possible, and is independent of the application program.

[0037] In the audio and video system provided by the prior art, the user's operation behavior on the audio and...

Abstract

The invention provides a data retrieval method and device, electronic equipment and a storage medium. The method includes: obtaining a target data type (the target audio and video behavior data is historical audio and video behavior data which is not stored in a database at present and is deleted from the database once) to which target audio and video behavior data of an audio and video application requested to be retrieved by a target user belongs; searching target audio and video behavior data from a block chain system used for storing operation data (the operation data comprises first operation data representing audio and video behavior data of the audio and video application) of the audio and video application according to the target data type. Based on this, the inquired target audioand video behavior data can be stored in the database, and the inquired target audio and video behavior data can be returned to the audio and video application so as to be convenient for a target userto check, so that retrieval of the audio and video behavior data deleted from the database once is achieved.

Description

technical field [0001] The present invention relates to the technical field of computer applications, and more specifically, relates to a data retrieval method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of communication technology, people's functional requirements for mobile phones, computers and other terminals are increasing, and various terminal-based applications are also increasing, especially audio and video applications have gradually become indispensable in people's daily work and life. A tool, the user's audio and video operation behavior in the audio and video application will generate the user's audio and video behavior data. [0003] In the prior art, the audio and video behavior data of the user is usually stored in the database by the audio and video server. When the user requests the audio and video application to query historical audio and video behavior data, the audio and video server directly...
