Abstract

The invention relates to a database index management method and device and electronic equipment, and relates to the field of cloud computing. The method comprises the following steps of determining whether a target node exists in an initial index of a database or not, the initial index comprising a first keyword; under the condition that that the target node is determined to exist in the initial index, determining a target sub-tree according to the target node and the newly-added data, wherein the target sub-tree is used for storing the newly-added data, the target sub-tree comprises a secondkeyword, and the second keyword is the unique identifier of the newly-added data; determining an update index of the database according to the initial index and the target sub-tree; and managing the data in the database according to the update index of the database. The processing speed of adding, modifying, deleting, checking and the like on the database is increased, and the performance overheadof equipment is saved.

Description

technical field [0001] The present invention relates to the technical field of databases, and more specifically, to a database index management method, a database index management device, and an electronic device. Background technique [0002] A database is a warehouse that organizes, stores, and manages data according to the data structure. It is an organized, shared, and uniformly managed collection of data stored in a computer for a long time. There are usually massive amounts of data stored in the database. In order to manage the data quickly and conveniently, the method of establishing a database index is usually adopted. An index is a structure that sorts the values ​​of one or more columns in a database table, using an index to quickly access specific information in a database table. [0003] Indexes are built based on specific keywords. In some scenarios, there are situations where the keywords of a large amount of data are exactly the same, and the keywords of oth...
