Along with the popularization of E-ticket, booking online or purchasing online has become the main trend of this industry. But the current E-ticket sales network company uses traditional BS model, and because of the increase of user, it’s a big pressure to Web server and network broad band. The load of Web server increasing leads the service ability of Web Services decreases rapidly. So how to lower the load of server, improve the speed of ticket inquiry, and provide a better interface to the users becomes a primary problem.Nowadays, AJAX and Web Services develop quickly. The appearance of AJAX enhances the Web users’experience, and AJAX has the following characters: quick operating response, good inter-action, lighter Web load…Web Services is the centre of next generation system, which is open, multi-platform and so on.Firstly this article analyses all the Web frames, and points out the shortcoming of using AJAX or Web Services separately on web sales network, then brings forward the blue print, which is that AJAX transfers Web Services, using this blue print, the user’s side can use Web Services directly by AJAX engine, at the same time, transfer the XML result from Web Services to user side to process the managing work. One the user’s side, XML is transferred to HTML, and then the client can see the result through browser.

The number of daily average flight inquiry is about 200,000 times, and the number of daily average sale ticket is about 5000 pieces, which occupies over 40% of Chongqing market, and its sub-agents are about 10000. Presently, this system’s annual average fault is lower than 4 times, the load of server and the spend of inquiry is better than the same networks.Therefore, the research of this article has a certain reference value on constructing high capability Web appliance.
