Electronic Commerce, usually is called e-commerce, conducts business on-line. It is electronic forms of communication that permits the exchange of sale information related to goods and services purchasing between buyers and sellers with digital cash and via Electronic Data Interchange (EDI). The application of e-commerce is very important because that is the only way that how buyers and on-line business stores make the deals without seeing and talking each other. The applications should be very friendly (interface with nice layout and easily accepted by the potential buyers), easy to access and use (almost without to learn any computer and network skills), showing all the necessary and related information to all the viewers (no any questions could not be found during purchasing), and trusted by real buyers (secure without the personal information leaking to third party especially social secure number and financial information). The well know on-line solutions are from IBM’s WebSphere Commerce Suite, Microsoft Corp’s Site Server Commerce Edition, Yahoo’s Yahoo Store, and BroadVision’s One-to-One Commerce, and all of them use web secure protocols such as S-HTTP (Secure HyperText Transfer Protocol), SSL (Secure Sockets Layer), or SEPP (Secure Electronic Payment Protocol). E-commerce has a lot of benefits if it compares with long time traditional business - less expense, space saving, spread fast, saving shopping time, easy comparison, almost no sales tax, etc..
