Abstract

The embodiment of the present application provides a data update method and device, which are applied to the server, by receiving the data update request sent by the user through the client; determining the first timestamp of the user data table of the server, and the first timestamp is the The maximum timestamp in the timestamp of the last update of each user data item in the server user data table; obtain all update data items in the update log table whose generation timestamp is later than the first timestamp; for For each update data item, use the update data item to update the server user data table, and determine the generation time stamp of the update data item as the user updated by the update data item in the server user data table The timestamp of the last update of the data item; the method of updating the client user data table indicated by the data update request based on the updated server user data table reduces the problem of excessive system load on the basis of realizing data update the occurrence of the situation.

Description

technical field

[0001] The invention relates to the field of computers, in particular to a data updating method and device. Background technique

[0002] With the popularity of the Internet, real-time sharing and synchronization of information is becoming more and more important. However, due to the asymmetry of each client, it is impossible to work in the P2P mode, and can only work in the client / server mode.

[0003] The current client / server mode is mainly to set the corresponding server user data table on the server for each user, and set the corresponding client user data table on the client. When there is an update demand, directly update the server The user data table, and the method of synchronizing data between the client user data table and the updated server user data table, realizes data update. However, as the amount of data increases, although the current client / server mode can realize data update, it often leads to the problem of excessive system load. [00...
