Problems solved by technology

[0010] As far as the current database development speed is concerned, storing data in the form of rows is natural, convenient, and fast for OLTP; but for the support of OLAP, "row storage" does not solve problems such as a large number of indexes. method, especially when analyzing a large amount of data, the data processing efficiency of the row database system will be greatly reduced

Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0041] see figure 1 , is a method flowchart of the first embodiment of a database data processing method provided by the present invention.

[0042] In the first embodiment, the described data processing method of a database mainly includes the following steps:

[0043] Step S101: the master node server receives a data processing request from a client, where the data processing request includes a data storage request. During specific implementation, the client sends a data processing request to the master node server; the master node server executes the next data processing according to the data processing request sent by the client. Wherein, when the data processing request is a data storage request, that is, when the client sends data to be stored to the master node server, ...

Abstract

The invention discloses a data processing method of a database. The data processing method comprises the following steps that a main node servo receives a data processing request of a client, wherein the data processing request comprises a data storage request; the main node server receives data to be stored; the main node server extracts various field values of one field of the data to be stored, calculates corresponding hash values and determines a storage position corresponding to each hash value; the main node server transmits the data to be stored and the hash values to a data node server; the data node server stores line data corresponding to the hash values into a corresponding main hard disc; and the main node server carries out mirror image back-up on the data stored in the data node server, wherein the data processing request also comprises data retrieval requests. The data processing method of the database, disclosed by the invention, is high in data processing efficiency and larger in capacity, and avoids the happening of single-site faults in a cluster.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a database data processing method. Background technique [0002] Database technology has been developed for more than 30 years since the late 1960s, and its main purpose is to effectively manage and access a large number of data resources. Database technology mainly studies how to store, use and manage data. Database technology is an important part of modern information science and technology, and the core of computer data processing and information management systems. [0003] The development process of database technology generally includes three stages: hierarchical database system, relational database system and object-oriented database system. The current database technology is mainly in the stage of relational database system. [0004] Database technology studies and solves the problem of how to effectively store and organize a large amount of data in the process of com...
