Abstract

The invention relates to the technical field of computer processing, in particular to a data recovery method, a data recovery device, a storage medium and electronic equipment. The data recovery method comprises the steps that when it is detected that a transaction is started, a data manipulation language of the transaction is analyzed to obtain an analysis result; generating a manipulation rollback statement of the data manipulation language according to the analysis result to obtain rollback information of the transaction; and in response to a data recovery instruction of the transaction, acquiring the rollback information to traverse and execute the operation rollback statement. According to the data recovery method provided by the invention, the data recovery applicability is high, and management and maintenance are convenient.

Description

technical field [0001] The disclosure relates to the technical field of computer processing, and in particular to a data recovery method, a data recovery device, a storage medium and electronic equipment. Background technique [0002] Today's Internet generates massive amounts of data, and storing data in one database will cause performance bottlenecks. Data is often split and stored in multiple databases, and one operation data falls into multiple databases, which means that the database itself cannot guarantee the operation of multiple databases. Transactions, so unpredictable situations often occur during execution, resulting in data errors that require recovery. [0003] There is no unified standard for data recovery, which needs to be handled by the developers themselves. However, the granularity of the data recovery technology of each database product is relatively coarse, and data recovery technology based on DML ((Data Manipulation Language, Data Manipulation Languag...
