Embodiment 1

[0031] Use MyEclipse 5.5 software development tools to develop client and server running software, use special database management tools on the market, Oracle 9i to build a central database, and use Sqlite to build a local business database. The specific methods are:

[0032] Offline applications are realized through the local offline engine subsystem and server subsystem, and the two subsystems include the following modules:

[0033] The local offline engine subsystem includes the following components:

[0034] ——Local database: use small text database, this system uses SQlite database to store business data;

[0035] ——Local server: supports offline access to pages and data storage;

[0036] ——Synchronization module: complete the synchronization of local data and server-side data and provide policy support for the synchronization process;

[0037] ——Transmission module: supports data processing and implements various transmission protocols;

[0038] ——Status detection mod...

Abstract

The invention relates to an offline application system, and particularly relates to an offline application system based on timestamp, belonging to the technical field of communication. The offline application system based on timestamp is characterized by consisting of a local offline sub-system and a server sub-system and is also characterized by storing local business data in a local database, supporting access of a client in an offline state through a local server, finishing synchronization between the local data and the central data through a synchronous module, finishing the matching of a transport protocol through a transport module, finishing the detection of the network state of the client through a state detection module, performing data storage and server timestamp management through a central database, loading and running each module through a central server and checking the consistency between the local timestamp and the server timestamp through a timestamp verification module. The system provided by the invention solves the problems that the prior art adopts one-way transmission and the offline data can not be stored and synchronized.

Description

technical field [0001] The invention relates to an off-line application system, in particular to an off-line application system based on time stamps. The invention belongs to the technical field of communication. Background technique [0002] With the development of communication technology, the delivery and use of various business application systems began to change, and a business system application model SaaS based on cloud computing began to be gradually accepted by users. The business application system of the SaaS model is fundamentally different from the delivery and use of existing systems. Individual users no longer need to install and implement the system independently, but only need to customize and use the functions provided by the system as needed, and use the system functions through the Internet. However, due to the instability of the network, the security of data usage in the business system is affected, so the offline application becomes the best solution t...
