Problems solved by technology

[0003] However, historical data will take up a lot of space. For example, in the field of electric energy meters in base stations, the energy information of electric energy meters in base stations has 2 million pieces of data per day for every 1,000 collection terminals (each terminal is connected to 100 electric meters). After one year of operation, the size of the database is also nearly 1TB. At this time, the query history is frequently slow, and the timeout alarm prompt is often displayed on the browser side
However, it is sometimes meaningless to save all the data for a long time. For example, the electricity consumption information of a single user 10 years ago may not need to be saved, at least it does not need to be saved in the system, as long as it is stored in a fixed hard disk Just in

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0018] ginseng figure 1 As shown, the database and the database management system are stored in the same server. Periodically, the server detects the generation time of a piece of data in the system, and a time limit is preset in the system. The time limit may be a point in time or time bounds. In one embodiment, it is a time limit, such as two years. When the generation time of a piece of data is detected, it is compared with the time limit. If the generation time is shorter than two years, no processing is performed. If the generation time is longer than two years, the data will be removed from the ...

Abstract

The invention provides a system data management method. The method includes the steps of detecting generation time of a piece of data in a system; comparing the generation time of the piece of data to a time threshold preset in the system; if the generation time of the piece of data is shorter than the time threshold, skipping the processing; if the generation time of the piece of data is longer than the time threshold, removing the piece of data from the system. Through the application of the method, the data stored long time ago can be removed from the system, space of the system is released, and the system can operate more stably and reliably.

Description

technical field [0001] The invention relates to the field of data management, in particular to a system data management method for regularly detecting and clearing data in the system. Background technique [0002] During the development of human society, the preservation of past data is always a crucial issue. With the development of society, the amount of data is also increasing. Now people are accustomed to using databases for data storage and management. Computers have been well promoted in our country, and all kinds of computers can be seen in all walks of life; in addition, with the development of random software technology and the actual needs of modern management, many organizations and individuals also need to manage computer databases. At present, the database has been widely used in various systems. In the actual business system, historical data needs to be saved, because firstly, it is necessary to perform backtracking queries to check the performance of a peri...
