Abstract

This application discloses a data synchronization method, which is applied to data synchronization between heterogeneous databases. The method includes that the terminal device records the primary key, attribute information, version number and synchronization status of the data object through the first storage format, and the cloud device records the data object through the first storage format. The second storage format records the primary key, attribute information, and version number of the data object, and then the terminal device and the cloud device realize data synchronization between heterogeneous databases based on their respective storage formats and version numbers. The technical solution of the present application can ensure the consistency of data synchronization between heterogeneous databases through, for example, version number management and synchronization state management.

Description

technical field [0001] The present application relates to the technical field of data synchronization, and in particular to a data synchronization method and device. Background technique [0002] With the popularization of various terminal devices, users may have multiple terminal devices, such as multiple mobile phones. Usually, a contact is added on a mobile phone, and the contact information is preferably automatically synchronized to other devices, so that it is not necessary to input the same information on each mobile phone, which is convenient for the user. If a user does not have multiple terminal devices, some data on the terminal side needs to be backed up to the cloud side to ensure data reliability. For example, contact information, if the mobile phone is lost and there is no backup storage, the contact information cannot be restored. Mobile phones are constantly being updated. Some users may replace a mobile phone in two or three years. When replacing a mobile...
