Embodiment 1

[0025] An offline system data synchronization method related to the present invention needs to divide the whole system into two parts, one is a local application system, and the other is a server system, and the two subsystems also include the following parts respectively:

[0026] The local offline engine subsystem includes the following components:

[0027] ——Temporary data storage files: use different local database application systems for different models to realize the temporary storage function of local data;

[0028] ——Network status detector: judge whether the current system is offline or online;

[0029] ——Time stamp generator: According to the requirements, obtain the time and time, and mark the events corresponding to the time;

[0030] ——Data synchronization module: complete the synchronization of local data and server data, support two-way synchronization, that is, upload data and download data, and include logic error correction function during data synchronizat...

Abstract

With the development of emerging technologies such as Internet, mobile Internet, cloud computing, big data and the like, the use mode of various service application systems starts to change. More andmore applications for a mobile terminal are provided, but data use of a service system can be influenced due to instability of a mobile network, so that a data synchronization problem of an off-line application solves the technical barrier of the current mobile Internet software development. A universal off-line application technology is completed based on a server, and data synchronization situation judgment is carried out by the server, the technology has larger requirements for configuration of the server, network bandwidth and other hardware devices, and the use defects exist. The invention provides an off-line system data synchronization method, a time stamp is marked through interaction information between the server and a client at the client, and the time stamp serves as a condition for judging whether synchronization is needed. When the client is in an off-line state, the information is stored in a local database, a time stamp difference is judged when the network is restored,data synchronization is carried out, and the off-line system application is realized.

Description

technical field [0001] The invention relates to a data synchronization method, in particular to an offline system data synchronization method. Background technique [0002] With the development of emerging technologies such as the Internet, mobile Internet, cloud computing, and big data, the use of various business application systems has begun to change. There are more and more mobile terminal applications, but due to the instability of the mobile network, the use of business system data is affected. Therefore, solving the data synchronization problem of offline applications has become a technical obstacle to the development of mobile Internet software. [0003] The more common offline application technology is based on the server, and the server judges the data synchronization status. If the network is smooth, the data content will be pushed to the client. If the network is not smooth, the corresponding client is offline, and the session will be reserved in the server. Re...
