Application And Research Of Network Database Based On Ajax

With the development of computer application technology, there comes a new kind of application architecture, called rich Internet application, referred to as RIA. RIA is a wen-based B/S architecture, a combination of C/S architecture and B/S architecture advantages. RIA'core is rich client, witch provid a rich user interface and asynchronous communication way to background application server, solve the B/S architecture of the disadvantages and enhance the user experience of Web applictions. Because of the advantages of RIA, the major IT companies have launched RIA client technologies, some groups have also launched the open-source technologies, to choose a suitable client-side technology to develop high-quality the RIA client with a relatively small cost, become a problem to Web developers.In this paper, introduced the RIA and Ajax technology concept at first, analysis the advantages of Ajax framework and compare various frameworks technology, selected Ext and ASP.NET Ajax framework for more analysis and research, in order to find the best framework for Web project on the.NET platform. Then, based on previous research, combined the Ajax technology with network database, propose a new mechanism for asynchronous access to the database, whitch make the user experience be improved. At the end of this paper, there is a practical application of Ajax technology. Designed and implemented a Web-based instant chat tool, which used a lot of Ajax technology to achieve asynchronous interaction.Finally, concluded the main research of this paper, and give a outlook of RIA and Ajax development trends and the next step of work.
