Problems solved by technology

In reality, there are often customers who need both frequent OLTP and frequent OLAP. For this reason, they have to deploy two or more sets of products to meet business needs, which not only brings higher investment costs, but also In practical applications, data migration between different products is required, which brings additional management and maintenance costs

Abstract

The invention discloses a large-scale parallel processing row-column mixed data storage device and a storage and query method, belonging to the technical field of databases. The device of the invention comprises an online transaction processing module, an online analysis processing module, a storage module, a cross-layer query module and a cross-layer interaction module. The present invention realizes two functions of OLTP and OLAP in one database at the same time, can store data in an appropriate form according to the access frequency of the data, can not only provide users with convenient query services, but also provide users with efficient data analysis services , which is an important technical progress compared to the way of deploying OLTP and OLAP separately in the prior art.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a large-scale parallel processing row-column mixed data storage device and a storage and query method. Background technique [0002] Massive Parallel Processing (Massive Parallel Processing, MPP) can make the same command be processed on multiple processors at the same time through coordinated calls to multiple processors, thereby greatly improving computing power. The main feature of MPP is that multiple processors perform calculations in parallel at the same time, and real-time communication between processors is possible. Due to the excellent scalability and powerful computing and processing capabilities of MPP, MPP has been used in large-scale mathematical modeling, database processing and other fields, especially the database management system (DataBase Management System, DBMS) using MPP technology has been used in It has been widely used in the prior art. [0003] Gener...
