Problems solved by technology

Due to the above reasons, in the existing technology, the data is directly queried from the DB server, and there is a problem of low data query efficiency
[0003] In addition, in the prior art, since all data is stored through the DB server, when the amount of data to be stored is too large, it is necessary to expand the capacity of the DB server
Due to the complex structure of the distributed database, it cannot be directly expanded, so the expansion process of the DB server is very complicated

Abstract

The invention relates to a data management method and system. The method comprises the steps of: receiving a data writing request and to-be-written first data, which are sent by a client; writing thefirst data to a database (DB) server according to the data writing request; obtaining second data within a preset time length before a preset time node from the DB server; and storing the second datain a file server and recording the corresponding relationship between the second data and the file server. According to the scheme, the data within less than a preset time length after the preset timenode are stored in the DB server; all the data before the preset time node are stored in the file server in units of the preset time length; the data before the preset time node are all queried and read from the file server; and a system can be easily expanded by adding the file server at the same time.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a data management method and system. Background technique [0002] In the existing Internet of Things, data storage and reading are often done through DB servers deployed in clusters. In the process of using the DB server for data storage and reading, since the DB server needs to satisfy both writing and reading, there will be a problem of read-write conflicts. In order to solve the problem of read-write conflicts, there will be a locking process. Due to the above reasons, in the existing technology, data is directly queried from the DB server, and there is a problem of low data query efficiency. [0003] In addition, in the prior art, since all data is stored through the DB server, when the amount of data to be stored is too large, it is necessary to expand the capacity of the DB server. Since the distributed database has a complex structure and cannot b...
