Embodiment Construction

[0075] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0076] figure 1 A schematic structural diagram of a physical storage manner of a database involved in the data set connection method provided by the embodiment of the present invention is shown. The database structure includes multiple data sets, each data set contains multiple data subsets, and each data subset can be divided into multiple sub-blocks.

[0077] In order to achieve efficient connection between different data sets and reduce the search time of matching data records between different data sets, it is particularly important to improve data extraction performance. Such as figure 1 As shown, in the process of database storage management, data records can be assigned to different data subsets one by one according to certain...

Abstract

The invention discloses a method and a device for aggregating and connecting data as well as a database system, and belongs to the technical field of the databases. The method comprises the steps of dividing each of a plurality of data sets into a plurality of subsets, taking one of every two data sets as a first data set and the other one as a second data set, matching data records in the data subsets of the first data set with data records in the data subsets of the second data set one by one, connecting the matched data recorded until the data records of all the data subsets of the first data set and all the data subsets of the second data set are collected, and outputting the connected data recorded. The method for aggregating and connecting the data is capable of effectively solving the problems of low data connection performance and high hardware configuration requirements of an existing data set connecting method.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a data set connection method, device and database system. Background technique [0002] With the development and growth of modern enterprises, the information data accumulated by enterprises has also increased dramatically. However, the information data accumulated by enterprises is often diversified and scattered. They may come from different functional departments and store business information of different dimensions of the enterprise. If an enterprise wants to extract valuable information from a large amount of scattered data, it must correlate, integrate and analyze these data information to form a relatively comprehensive and valuable data set. In order to facilitate the effective management of these massive data, the data warehouse management system has gradually been widely used. Extract, transform, load (English: Extract, Transform, Load; abbreviation: ETL) tools are...
