Embodiment Construction

[0037] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0038] In the process of building a database, the basic information of a large amount of data needs to be stored in the database, so that the basic information of the data can be queried later. In the prior art, the basic information of a large amount of data is directly stored in the database, but there may be a large amount of identical or similar information in the basic information, which...

Abstract

The invention provides a data storage method and device, electronic equipment and a storage medium, and the method comprises the steps: determining a similarity index between to-be-stored data and each piece of index data based on the metadata of the to-be-stored data and the metadata of each piece of index data in an index metadatabase; when the similarity indexes between the to-be-stored data and the index data are all smaller than a similarity threshold value, basic information of the to-be-stored data is stored in the index metadatabase. The problem that the basic information of the to-be-stored data which is repeated or similar to the index data is stored in the index metadatabase, and consequently the storage space of the index metadatabase is occupied can be avoided. Besides, the to-be-stored data is different from other index data in the index metadatabase, so that the user can uniquely query the to-be-stored data in the index metadatabase, and the problem that the query efficiency is relatively low due to the fact that the user needs to screen multiple pieces of similar index data is avoided.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data storage method, device, electronic equipment and storage medium. Background technique [0002] At present, in order to query data conveniently and quickly, the query is mostly performed in the index database based on the mapping relationship between the metadata and the basic information of the data. [0003] In the process of building a database, the basic information of a large amount of data needs to be stored in the database, so that the basic information of the data can be queried later. In the prior art, the basic information of a large amount of data is directly stored in the database, but there may be a large amount of identical or similar information in the basic information, resulting in a large amount of redundant data in the database, wasting the storage space of the database. Contents of the invention [0004] The present invention provides ...
