Embodiment

[0030] 1. Data writing

[0031] The steps for the client to write data to the database are as follows:

[0032] 1. The client packs and compresses the data to be sent to the access layer of the database;

[0033]2. The database access layer decompresses the data packets sent by the client after receiving them, then repackages the data packets according to the built-in distribution algorithm, and then sends the repackaged data packets to the corresponding data layer;

[0034] 3. After the corresponding data layer receives the data packet, it first parses the data and then saves it to the disk.

[0035] 2. Data reading

[0036] The steps for the client to read data from the database are as follows:

[0037] 1. The client sends a read command (including query parameters);

[0038] 2. After the database access layer receives the read command, it parses the query parameters in the command;

[0039] 3. The database access layer splits the query instructions according to the bui...

Abstract

The invention discloses a server cluster-based parallel real-time database. The database comprises a client and a database system. The database system comprises an access layer, a data layer, an access layer server and a data layer server. The client calls a modification method, a query method, a real-time data storage method and a real-time data query method of the database to perform historical data modification, historical data query, real-time data storage and real-time data query respectively through an external interface, wherein two or more small servers are arranged in each of the access layer server and the data layer server. The average allocation of data in the servers is realized by utilizing a data allocation balance algorithm. According to the server cluster-based parallel real-time database, a conventional database technology, a server cluster technology and a memory database technology are combined, and the average allocation of the data in the servers is realized by utilizing the data allocation balance algorithm, so that the storage and query speed is increased to the maximum extent.

Description

technical field [0001] The invention relates to the field of informatization, in particular to a parallel real-time database based on server clusters. Background technique [0002] With the wave of global informatization and the continuous expansion of computer application fields, the application of databases has developed from traditional fields to new fields, such as network management such as data communication, telephone exchange, power dispatching, electronic banking affairs, electronic data exchange and electronic Business, securities and stock trading, traffic control, radar tracking, weapon guidance, real-time simulation, combat command and other military applications, automatic storage, real-time data collection and analysis monitoring and other engineering processes. These application activities have a strong timeliness, requiring processing to be completed within a specified time and within a certain period of time, and a large amount of data must be shared and co...
