Embodiment 1

[0071] An embodiment of the present invention provides a method for improving data information integration efficiency.

[0072] On the one hand, if figure 2 As shown, the method includes the following steps:

[0073] 101. Obtain a query command; the query command includes a query condition and a field targeted by the query command.

[0074] An example is now used to illustrate the relationship between the query conditions included in the query command and the fields targeted by the query command. Example 1, assume that the data information in the database is stored in data tables A, B, and C, such as image 3 shown. The data information stored in data table A is stored under fields a1 and a2, the data information under field a1 has 10, 20, 30, and the data information under field a2 has 15, 25, 35; the data information stored in data table B Stored under fields b1 and b2, the data information under field b1 is 10, 25, 30, and the data information under field b2 is 13, 25,...

Embodiment 2

[0103] An embodiment of the present invention provides a method for improving the efficiency of data information integration, such as Figure 5 As shown, the method includes the following steps:

[0104] 301. Obtain a query command; the query command includes a query condition and a field targeted by the query command.

[0105] 302. Decompose the query command into query subcommands according to the query condition.

[0106] 303. Detect whether the data table where the field targeted by each query subcommand has a preset optimization integration flag.

[0107] There are two types of data tables where the fields targeted by the query subcommand described in step 303 are located. One is a data table with a preset optimization integration flag, that is, an optimized data table, and the other is a data table without a preset optimization integration flag. The data table of , that is, the non-optimized data table. For a data table with a pre-set optimization integration flag, fo...

Embodiment 3

[0129] On the one hand, an embodiment of the present invention provides a device for improving the efficiency of data information integration, such as Figure 7 As shown, the device includes:

[0130] The command acquisition unit 41 is configured to acquire a query command; the query command includes a query condition and a field targeted by the query command.

[0131] The command decomposing unit 42 is configured to decompose the query command into query sub-commands according to the query conditions.

[0132] The field data information obtaining unit 43 is configured to obtain the field targeted by the query subcommand in the database according to each query subcommand, and obtain the data information under the name of the field targeted by the query subcommand.

[0133] The data information obtaining unit 44 is configured to obtain data information meeting the query condition by filtering the data information under the field name targeted by the query subcommand.

[0134] T...

Abstract

The embodiment of the invention discloses a method and a device for increasing integration efficiency of data information and relates to the field of a computer. The technical problems of low calculation efficiency and high cost of storage resource in the prior art are solved. The method for increasing the integration efficiency of the data information comprises the following steps: decomposing an acquired inquiry command into an inquiry subcommand and respectively obtaining a field and the data information under a field name aiming at the inquiry subcommand from a database; selecting the data information under the field name directed by the inquiry subcommand, thereby obtaining the data information meeting an inquiry condition; and integrating the data information meeting the inquiry condition into an inquiry result. The method provided by the invention is mainly applied to the inquiry and storage of the data information.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and a device for improving the efficiency of data information integration. Background technique [0002] Scientific and targeted marketing decisions are inseparable from the support of objective data information, which makes users have higher requirements for the speed of data information integration. [0003] In the prior art, the relational database integrates data information through a "binary tree", that is, the system first decomposes the query command into N query subcommands, and the computer retrieves the data table corresponding to each query subcommand in the database to find to the data information that meets the requirements of each query subcommand. Specifically, first find the data tables corresponding to the first query subcommand and the second query subcommand, and find the data information that meets the requirements, and then merge the data information that m...
