Abstract

The invention discloses a data query method and device which are applied to a system server. The system server is connected with a data server. The device is characterized in that keyword files which are generated according to a database of the data server are stored in the system server. The method comprises the following steps: receiving a query instruction transmitted from a user terminal, wherein the query instruction comprises query keywords; analyzing the query instruction to obtain the query keywords; searching the keyword files according to the query keywords to obtain a keyword query result which corresponds to the query keywords; and returning the keyword query result to the user terminal and then displaying the keyword query result. The keyword files in the system server are queried according to the query instruction of the user terminal, data are not operated directly, even if lots of data are queried, performance of the database is not affected, and paralysis of a server of the database is avoided.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, relates to a data query method and device. Background technique [0002] When users need to query the information they want to know, they usually need to obtain the information they need to query by querying the database. [0003] For example, when inquiring about stock quotes, the user inputs an inquiry instruction through the user terminal, including the stock code "1", and sends it to the system server communicating with the user terminal. After receiving the inquiry instruction, the system server inquires the database in the data server connected to it. , get the stock information related to the stock code "1" as the query result, and return it to the user terminal. [0004] However, this query method will directly operate the database. When multiple queries are performed at the same time, the query operation will be performed on the data at the same ti...
