Abstract

The embodiment of the invention discloses an operation undoing method and device and an electronic device. The operation undoing method comprises the steps that an operation undoing request of a to-be-undone operation executed to updated data is received; responding to the operation undoing request of the to-be-undone operation, inverted sequence operating information corresponding to the to-be-undone operation is obtained, wherein the inverted sequence operating information is used for representing operating information obtained in complete inverted operation conducted on the positive sequence operating information corresponding to the to-be-undone operation; the operation is executed according to the inverted sequence operating information to obtain original data. According to the embodiment, the updated data is operated according to inverted sequence operating information by obtaining the inverted sequence operating information corresponding to the to-be-undone operation, the original data after the to-be-undone operation is undone is obtained, the undoing operation is easier to execute by obtaining the inverted sequence operating information, and the method is suitable for frequent undoing operation. The flexibility of data undoing operation is improved, any quantity of data updating operations at any moment is support, and the cost for the data undoing operation is greatly decreased.

Description

technical field [0001] The invention relates to data operation technology, in particular to an operation revocation method and device, and electronic equipment. Background technique [0002] Database (Database) is a warehouse that organizes, stores and manages data according to the data structure. It was produced more than 60 years ago. With the development of information technology and the market, especially after the 1990s, data management It is no longer just storing and managing data, but has transformed into various data management methods that users need. The data operations in the database are very frequent, but when an operation error occurs, it is necessary to undo the operation. At present, most of the existing database products realize the undo by backing up the database, that is, the database file is backed up every time. Save it once. When revocation is required, the current data is discarded and the previously saved data is read. [0003] In the process of i...
