Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] In one embodiment, such as figure 1 As shown, a data query method based on multiple databases is provided, and the method includes the following steps 102-108.

[0043] Step 102, the server obtains a query request, which carries query information, generates a query instruction according to the query request, and sends the query instruction to the central database.

[0044] In this embodiment, the query request may be a query request sent by a user terminal, or may be a query request automatically initiated by a background system, and the query request carries specific query information. Qu...

Abstract

The invention relates to a multi-database-based data query method. The method is characterized by comprising the following steps of obtaining a database query request, and generating a query instruction according to the query request, wherein the query request carries query information; determining a central task number and a plurality of corresponding sub-task numbers according to query information; sending the sub-task numbers to corresponding sub-databases, thereby enabling the sub-databases to obtain the query instruction according to the sub-task numbers; and receiving and collecting query results fed back by the sub-databases. According to the method, related information in the sub-task numbers can be queried once without querying the sub-task numbers one by one, so that the query efficiency is improved. In addition, the invention provides a multi-database-based data query system and apparatus.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a data query method, system and device based on multiple databases. Background technique [0002] Database is a system in computer application system that specially manages data resources. Data comes in many forms, such as text, numbers, symbols, graphics, images, and sounds. With the development of technology, a large amount of data can usually be stored in a database. [0003] However, for some companies with a large amount of business data or widely distributed business data, multiple databases are usually set up for the convenience of management. For the above situation, when it is necessary to obtain relevant data in the multiple databases, the traditional query method usually needs to query each database one by one, and then summarize the queried data, and the query efficiency is not high. Contents of the invention [0004] Based on this, it is necessary...
