Abstract

The invention provides a database management system, which is applicable to the technical field of a database. The database management system comprises a request queuing machine, a memory node and a disc node, wherein an external service request is simultaneously delivered to the memory node and the disc node through the request queuing machine; the memory node comprises a memory data application layer, a memory data access layer and a memory database; the disc node comprises a disc data application layer, a disc data access layer and a disc database; the memory data application layer and the disc data application layer have the same service logic function objects; the memory data application layer and the disc data application layer respectively call the same service logic function objects according to the external service request at the same time, the service logic processing is realized, and processing results are obtained; the memory data application layer and the disc data access layer respectively write the processing results into the memory database and the disc data base at the same time. The database management system has the advantages that the advantages of the two databases are sufficiently realized, and wide application values are realized in financial industry with higher requirement on transactional consistency.

Description

technical field [0001] The invention belongs to the technical field of databases, in particular to a database management system. Background technique [0002] Traditional database management systems store all data on disks for management. When accessing disk databases, frequent access to disks is required for data operations. Due to the operation of reading and writing data on the disk, on the one hand, the mechanical movement of the magnetic head (except for solid-state hard disks) is required, and on the other hand, it is affected by the time of the system call (usually completed through CPU interrupts, restricted by the CPU clock cycle). When the amount of data When the read and write operations are frequent and complex, the problem of insufficient performance will be exposed. [0003] The memory database system is a redesigned database management system that uses CPU cycles and memory more efficiently by redesigning the algorithms and data structures of query processing...
