A Heterogeneous Data Synchronization Method Based on Incremental Update on Mobile Devices

Abstract

The invention belongs to the data processing field of mobile electronic devices, and provides a heterogeneous data synchronization scheme, based on incremental updating, on a mobile device. A device-end data synchronization method includes the steps: taking out to-be-updated synchronous data list from a device end and obtaining to-be-synchronized data from the list; establishing a to-be-synchronized data parameter; sending the to-be-synchronized data to a server end and receiving a data response on the server end; and determining whether a clear identification and an ending identification exist, whether the number of data is 0, and whether the number of data is all 0. A server-end data synchronization method includes the steps: receiving a data synchronization request; cycling a to-be-synchronized data parameter in the synchronization request; searching for the updating direction of to-be-synchronized data; checking the to-be-synchronized data at the earliest synchronization time and at the latest synchronization time, and forming a data list; obtaining an external clear instruction and forming a data response; and returning the data response to the device end. Simultaneous data synchronization of various types of heterogeneous data can be achieved, the data updating scale is controllable each time, and fault tolerance is allowed.

Description

technical field [0001] The invention belongs to the field of data processing of mobile electronic equipment and can be used for high-efficiency data synchronization between servers and mobile electronic equipment. technical background [0002] Mobile electronic devices often have the need to maintain data synchronization with the server, usually through TCP or HTTP protocol for data transmission, and implement a business layer protocol on top of this to achieve the goal. Some of the previous solutions and the solutions in this article are all business layer protocols built on the network, transport layer or application layer. The closest prior art to the present invention includes a full update technical solution and a simple incremental synchronization technical solution. [0003] The solution for full update means that all data needs to be pulled from the server for each synchronization, and the local data is directly overwritten to achieve the purpose of data synchroniza...

AI Technical Summary

Problems solved by technology

Its disadvantages are: each update has a large amount of data, the waiting time is long, and the calculation pressure on the server and mobile devices is relatively high

This method only works on one type of data, and cannot synchronize multiple types of data at the same time, and in extreme cases, a single update of huge amounts of data and data errors cannot be recovered
