Abstract

The invention provides a data recovery method and device applied to a database. The method includes the steps that a data recovery request is received; binary system log information corresponding to the data recovery request is determined; the binary system log information is analyzed and converted into first text information; the first text information is reversely analyzed and converted into second text information; data are recovered based on the second text information. According to the scheme, as only the binary system log information in the time interval to be recovered is converted, the data processing amount is greatly reduced, and the data recovery time of the database is effectively shortened; when data misoperation and other conditions occur, the duration for interrupting front end service can be shortened, and the use influence on a front end user is greatly reduced.

Description

Technical field [0001] The present invention relates to the field of computer technology. Specifically, the present invention relates to a data recovery method and device applied to a database. Background technique [0002] In the information age, the importance of data to people is self-evident, and then a database that organizes, stores and manages data according to the data structure has emerged. Database technology is the core part of various information systems such as management information systems, office automation systems, and decision support systems, and is an important technical means for scientific research and decision management. Many system applications use a database to store various information. The applications in the system can write information to the database through database commands, and can also read required information from the database through database commands. Therefore, the data stored in the database is of extremely high importance. If a user miso...
