In the nineties of the 20^th century, Web1.0B/S (Browse/Server) application appears with the fast development of Internet. The limitation of high-cost deployment and difficult update is broken by the widely use of Web B/S application framework.

A RIA (Rich Internet Application) framework is introduced to design and realize presentation layer.Adobe Flex technology under RIA framework is chosen to realize part-update effection, lower data exchange and rich user experience.
