Problems solved by technology

This kind of data transfer between nodes during query is also called dynamic repartitioning (Dynamic Repartitioning), which will not only consume network bandwidth, but also generate time-consuming transmission, greatly increasing query response time and affecting query efficiency.

Embodiment Construction

[0024] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0025] When building a database system or a data warehouse based on a distributed database, the actual fact data and the data used to describe attributes are generally separated by different tables, and the actual fact data is stored in a class called fact Table (Fact table), and data describing attributes from different perspectives are placed in different dimension tables (Dimension table). For example, a Sales database or data warehouse can be designed like this. Each sales record should include the product sold, the customer sold, the supplier of the product, the time of sale, the quantity sold, and the income obtained. For specific digital data such as sales qu...

Abstract

A data partitioning method for a distributed parallel database system, comprising creating fact tables and dimension tables according to a constructed distributed parallel database system, inserting records of the dimension tables and the fact tables into nodes according to partitioning rules, replicating the records of dimension tables into the nodes that include fact tables, performing data deletion, and performing data update.

Description

technical field [0001] The invention relates to a distributed parallel database system, in particular to a data partition method of the distributed parallel database system. Background technique [0002] Storing data in databases is a common method of data management, especially in relational databases. We can choose a mature database management system (DBMS: Database Management System) according to the data needs to be managed, and use a standard data definition language (such as SQL DDL) to define data tables (Table) or relations (Relation), data structures , index, primary key (Primary Key) and foreign key (Foreign Key) and other information of the database data management program (Database Schema), deploy the database system. According to the data manipulation language (such as SQL DML) provided by the DBMS, the application program can perform data manipulation, such as inserting, querying, updating, importing and exporting, etc. [0003] In many current industry appli...
