Description
Technical field
The present invention relates to technical field of data transmission, specially a kind of distributed multiterminal data transmission synchronization system and its side
Method.
Background technology
Existing business cash register software product, mainly the following two kinds pattern is taken in the design Storage of data；
A. local data base storage scheme is used；It is general to use what microsoft was provided on windows machines
MSSQLSERVER technical schemes；When user carries out business operation, the operating result of data is stored in the database in the machine
In.The problem that storage scheme is present is the situation that may be only available for single machine.In the presence of having many machines, each other
Data cannot connect calculating.
B. the server database storage scheme of centralization is used；All of client machine, it is necessary to during data, from service
Device goes to obtain data；When data need storage, server end is also stored data into.This scheme can preferably meet many
The requirement that data are in communication with each other between equipment, not enough place is, when client machine needs peration data, it is necessary to have net
Network, and network connection keeps stabilization.If client machine without network, cannot complete normal business operation at that time.
The shortcoming of existing two kinds of data patterns:The first single cpu mode can only support scattered commercial accounts；The shortcoming of this scheme is as follows：
1. data are only stored in locally, it is impossible to do the backup of other machines, and when machine goes wrong, the data of user can also lose.
Such as member and payment data lose, and for many commercial accounts, this is unacceptable, and 2. data cannot be at other ends
Checked on end.With the development of mobile Internet, many commercial accounts wish at any time check the business of oneself on mobile phone
Data, the data integration that cannot be 3. produced with many other equipments is counted.When certain commercial accounts there are many business equipments, enter
The statistics of row data and check and will take time and effort；Second data storage scheme of centralization can support multiple terminals, multiplex
The data at family check requirement, but require that data acquisition end must keep presence at the moment.And this requirement is very harsh
And it is disagreeableness to user.Envision certain commercial accounts to be opened for business on underground square, but the network in shop is highly unstable, this
Scheme means that this commercial user cannot perform normal business operation, and the shortcoming of this scheme is as follows：1. all devices will be checked
Data, it is necessary to real-time online；2. when the terminal device of connection is a lot, the pressure of server is very big.When user checks data, meeting
Produce serious time delay phenomenon.
The content of the invention
It is above-mentioned to solve it is an object of the invention to provide a kind of distributed multiterminal data transmission synchronization system and method
