Data updating method

Abstract

The invention discloses a method for updating data, which is applied to the synchronous updating of the data stored in a client and a server, wherein, updating identification is configured for each data, the same storage data in the client and the server has the same updating identification; the method includes the steps that: a. the client transmits a data updating request to the server, the data updating request includes an updating category, and client data updating identification corresponding to the updating category; b. when the server receives the data updating request, the client data updating identification in the updating request is compared with the stored local data updating identification, the updated data meeting the preset updating conditions are determined according to the updating category, and an updating instruction containing the updated data information is transmitted to the user; and c. the client carries out the corresponding data updating after receiving the updating instruction. The method of the invention can efficiently carry out the updating of the row-level data at the client; and the downloading operation needs less bandwidth resource.

Description

technical field [0001] The invention relates to a data update method, in particular to a method for a client and a server to keep data synchronously updated, and belongs to the field of data communication. Background technique [0002] With the continuous development of electronic technology, computer technology and communication technology, as an information carrier, various clients, such as clients, have played an active role in various aspects, especially the ability to store various data makes people It is more convenient and faster to save and query data information at any time; however, with the increasing demand for stored data and the requirement for modification of stored information, it is usually required that the stored data of the client and the stored data of the server can be updated synchronously. [0003] In the prior art, in order to solve the above-mentioned problem of data update in the client, the following two methods are usually adopted: [0004] (1) ...

AI Technical Summary

Problems solved by technology

[0004] (1) An input device is set on the client, and the user directly adds the required new information to the corresponding item of the client by inputting, or modifies or deletes the existing information, but this method is completely input by the user, not only The error rate is high, and if multiple clients need to input the same information, it is a completely repetitive operation, and the input efficiency is very low;

[0005] (2) By setting up a server, the content to be updated is stored in the server. When the client initiates a data update request, the server will provide the data that meets the client data update conditions to the client through the network or other means according to a predetermined policy, but In this method, the server usually transmits an entire data packet to the client, and then replaces the data stored in the client with the data in the downloaded data packet. It can be seen that using this method, the bandwidth occupied by data download is relatively large. Data download time will also be longer
