Problems solved by technology

One is that the wireless network connection between the mobile computer device and the remote data server may be weakened or even interrupted due to other interference or too far away
The second is that when a large amount of data is transmitted between the mobile computer device and the remote data server, the transmission speed will be quite slow
When updating data, a weakened network connection may cause the updated data to become garbled
Moreover, the cost of a wireless connection is generally higher than that of a wired connection. If a user needs to be connected continuously, the cost of maintaining the connection may exceed the profit generated by the wireless connection.

Embodiment Construction

[0020] Such as figure 1 Shown is a hardware architecture diagram of a wireless communication system supporting the present invention. Currently, enterprise information systems generally adopt a three-tier (or multi-tier) architecture: multiple scattered front-end workstations, a series of application servers, and a central database server. In the present invention, the front-end workstation mainly adopts a mobile computer device, which may specifically be a Personal Digital Assistant (PDA), a laptop computer (Laptop Computer), or a smart phone (Smart Phone). In the following specific embodiments of the present invention, the present invention is described by taking the personal digital assistant 101 as a front-end workstation. The application server 103 contains the core and changeable business logic (planning, operation method, management mode, etc.) in the system, and its function is to receive input, process and return the result. The database server 107 is responsible fo...

Abstract

A mobile computer device and a data base server are connected through an application server, which can perform data filtering to the added and updated data in the data base of the data base server, the mobile computer device includes a connection switching over module, a data processing module, a data filtering device and a data synchronization module, wherein the connection switching over module can switch the connection link between the mobile computer device and the data base server. The system by the invention can reduce communication connection time during data synchronization and can cut down data transfer.

Description

【Technical field】 [0001] The invention relates to a data synchronization system and method, in particular to a system and method for synchronizing data in mobile computer equipment and data in a remote database server. 【Background technique】 [0002] Shortly after computers were invented, people started connecting them. Connections between multiple computers enable common resources such as printers and storage devices to be shared. At first, computers were connected by cables. With the development of technology and the increase of people's demand for flexibility, wireless communication methods appeared and developed. Early wireless communication technologies involved a periodic connection between a mobile device and a network port, which was accomplished by a cable or infrared signal between the mobile computer device and the network port. This technology needs to connect a cable to the network connection port on the mobile device, or set an infrared device on the mobile d...
