Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] refer to figure 1 , is a schematic structural diagram of an embodiment of a system for realizing multi-client data synchronization of the present invention; as figure 1 As shown, the system includes: a server 20, and at least two clients 10 (because the structures of each client are basically the same, only the client 1 is marked in the figure, and it is explained here that N is a natural number in the figure, representing There can be multiple clients).

Abstract

The invention discloses a method for realizing multi-client data synchronization. The method comprises the following steps that: a client receives an application request of a user, and determines the type of application data requested by the application request; according to the type of the application data, the client reads a last updating time T1 when the application data of the type is updated from a server; and the client compares the T1 with a last updating time T2 of the application data, of the type, stored by the client, synchronizes the application data of the type according to a comparison result, and responds to the application request according to the synchronized application data of the type. Correspondingly, the invention also discloses a client, a server and a system for realizing the multi-client data synchronization. The method, the system, the client and the server can ensure the data synchronization among a plurality of clients, and simultaneously, save time, reduce the occupation space of a memory of the system, and improve the performance of the system.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, a system, a client and a server for realizing multi-client data synchronization. Background technique [0002] In the network connection mode, a client / server (Clint / Server, C / S) structured network is another form of network different from a peer-to-peer network. In the C / S architecture, the server is the core of the network, and the client is the foundation of the network. The client relies on the server to obtain the required network resources, and the server provides the client with the resources necessary for the network. At present, the C / S architecture network plays an extremely important role in the existing Internet, providing people with rich services, such as address book management, chat history management, and so on. [0003] Since data exists on both the client and the server, the system needs to perform necessary data synchronization. In the existing technology...
