Our new evolutionary method allows electronic commerce (EC) services on distinct distribution channels. Launching EC services on the Internet require careful on mobile agents. It supports EC transition flows written in XML. Our algorithm resolves the concurrent data-accessing problem among EC services databases. To create a better algorithm, we have analyzed a variety of transaction schemes compatible with standards and developed a modeling framework on which maintaining good consistency. With our EC transaction method, we can make use of different techniques and organize an EC framework with clients, agents, and EC application servers all included form an integrated EC system management mechanism. Our proposed system can improve the relationship between EC service systems and transaction agents for supply-chain management.
