Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with examples and with reference to the accompanying drawings.

[0030] In the present invention, when creating a database, identification information is set for the data in the database, wherein similar data has similar identification information; when performing data query, the data to be queried is classified according to similarity; Similar identification information is used for data query in the database.

[0031] Regarding the similarity, it can be the similarity of the data categories. For example, in the city data, the urban population data exceeds 10 million is a super city, and "the population exceeds 10 million" is used as the similarity of the super city, and the same can be set for this type of data. Identification information, such as its identification is set to "100000", of course, these super ...

Abstract

The invention discloses a data query method. When a database is established, identification information is set for data in the database, wherein similar data have similar identification information. The method includes the steps of classifying the data to be inquired according to similarity when data query is conducted, and conducting data query in the database according to the similarity identification information corresponding to the classifications of the data to be inquired. The invention further discloses a device for achieving the method. According to the technical scheme, data do not need to be inquired step by step according to the recursive method when data query is conducted, the data to be inquired can be determined through similarity between the data to be inquired and the identification information corresponding to the similarity, and therefore query efficiency can be greatly improved, and the corresponding data can be rapidly and accurately inquired no matter what the number of nodes related to the inquired data is.

Description

technical field [0001] The invention relates to data query technology, in particular to a data query method and device. Background technique [0002] In the current data query technology, recursive query is the most common query method. Generally speaking, in recursive query, when the server receives a query request, it performs data query. If the server cannot directly query the corresponding result, it performs recursive query on the top and bottom of each branch in each tree of the domain, and finally returns the query result. [0003] Although the recursive data query technology can realize the effective query of data, it needs to consume a lot of resources when querying the data of the end node, the query operation is quite large, and the query efficiency will be greatly reduced. Contents of the invention [0004] In view of this, the main purpose of the present invention is to provide a data query method and device, which can efficiently perform data query. [0005...
