Problems solved by technology

[0002] In today's era of increasingly large and fast information, it is necessary to provide users with a large amount of fast and beneficial information. On the other hand, because the data of the centralized database in the past is stored in one place, it is slow to query and insert data, and it is limited by physical performance. , the physical equipment is also easily damaged, and the traditional database can no longer meet the needs of users

Embodiment Construction

[0019] The database system of the present invention connects the databases distributed in different places through the network, and abstracts it as the control behavior of "after the data operation passes through the front-end agent, it is transmitted to the specific data for execution in the form of forwarding".

[0020] like figure 1 , 2 As shown, the relational distributed database system of the present invention includes a data layer composed of multiple database nodes, a proxy layer and a connection pool layer. The proxy layer communicates with the data layer through the connection pool layer. The proxy layer converts the SQL statement of the external application program into an executable SQL statement, and determines the target database node for executing the SQL statement through a distribution algorithm; and passes the executable SQL statement to the connection pool layer. The connection pool layer is used to create and manage the connection between the proxy layer ...

Abstract

The invention discloses a relational distributed database system which consists of an agent layer, a connection pool layer and a data layer, wherein the data layer comprises a plurality of database nodes; the agent layer converts an SQL (Structured Query Language) statement of an external application into an executable SQL statement, determines the target database node executing the SQL statement, and transfers the executable SQL statement to the connection pool layer; the connection pool layer is used for creating and managing connection between the agent layer and the data layer, and transfers the executable SQL statement to the target database node executing the SQL statement; the target database node executing the SQL statement executes corresponding inquiry or executing operation and returns an executing result; and the result is returned to the external application through the connection pool layer and the agent layer. The system can realize high-frequency insertion and inquiry of a high-volume database.

Description

technical field [0001] The invention relates to a relational distributed database system, which is suitable for mass storage data and uses the CentOS operating system as the distributed database field for software development and operating environment. Background technique [0002] In today's era of increasingly large and fast information, it is necessary to provide users with a large amount of fast and beneficial information. On the other hand, because the data of the centralized database in the past is stored in one place, it is slow to query and insert data, and it is limited by physical performance. , the physical equipment is also easily damaged, and the traditional database can no longer meet the needs of users. In order to unify the development methods of distributed database systems, save time and labor costs, and speed up the rapid response cycle of the system, a network distributed database system suitable for the current rapid response needs is needed.
