[0070] The first preferred embodiment of the present invention takes a cooperative electronic shopping system as an example. Many members of a family shop online, each of them has a mobile smart phone, they choose the goods they need individually, and record the selected goods on their personal smart phones, and when they finally pay the bill, they pay together, so it is necessary "Merge" the goods purchased by individuals together, and then use one of the smartphones to make online payments. For example, member A buys 1 bottle of milk and 2 apples, and member B buys 2 bottles of milk. They record these information on their personal smartphones independently. When they want to pay, they first send these goods through the phone " Merge" together, the program merges the messages in the two mobile phones, and the result is 3 bottles of milk and 2 apples, and then A makes the final network payment. The program is mainly composed of Merchandise, Milk, Apple, Parser, ClientPanel, a...

Abstract

The invention discloses a middleware system for sharing data in mobile phone equipment and a working method. The system is applied to a system consisting of at least one server and more than two clients operating in the mobile phone equipment; the client comprise client item management units, client message conversion units, client buffer units, client communication units, client DOM operation units, client resolution strategy units and client conflict resolution units; and the server comprises a server message queue management unit, a server storage unit, a server communication unit, a server resolution strategy unit, a server DOM operation unit and a server conflict resolution unit. Through the data transmission and processing of the units, the two terminals can send messages to each other, process received messages and send the processed messages, the programs can roll back, and thus, the bidirectional synchronization of the messages between the two terminals is guaranteed.

Description

technical field [0001] The invention relates to a middleware system running on a mobile phone device, more specifically to a computer software system and a working method in a distributed environment composed of mobile phones. Background technique [0002] Wired network, also known as fixed network, is a relatively persistent physical network composed of a series of fixed hosts connected together through high-bandwidth network cables and networking equipment. Such an operating environment requires distributed applications to consider: (1) scalability, which refers to the ability to accommodate higher loads for a period of time in the future; (2) openness, which refers to the ability to update when functional requirements change Easy to expand and modify the system; (3) Heterogeneity means that the different components integrated in the distributed system are written in different programming languages, run on different operating systems, and run on different hardware (4) fau...
