Abstract

An embodiment of the invention discloses a method and device for high-performance query of a database. The method for high-performance query of the database comprises the steps of storing to-be-stored data in a buffer area of a system memory by executing data definition language (DDL); and enquiring about the data in the buffer area by executing data query language (DQL). According to the method and device for high-performance query of the database, data query efficiency of a database system can be remarkably improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of databases, in particular to a high-performance query method and device for a database. Background technique [0002] A database is a warehouse that organizes, stores and manages data according to its data structure. The concept of database was born in the 1960s. With the development of information technology and time, especially the vigorous development of the Internet in recent years, database technology has also been widely used. Today, most applications deploy database systems in the background. [0003] Existing database systems usually store data on the system hard disk when storing data, and when users need to query the data in the database system, they need to read data from the system hard disk. Reading data from the system hard disk will cause physical input and output (IO) of the hard disk. Because the physical IO of the system hard disk takes a certain amount of ti...
