| With the popularity of the Internet and the rapid development of information technology, Web application has become an integral part of the information age. Ajax (Asynchronous JavaScript and XML) is a new interaction method between server and client side, asynchronous interactive technology is involoved with Web applications, so that applications could give users more efficient response and a good user experience.Since the concept of Ajax was first put forward, increasing number of web applications use Ajax technology to improve user experience. At the same time, Ajax technology are widely used in enterprise-level area, Microsoft, IBM Corporation, Google Inc. and other large software providers are all developing their own Ajax development platform, so that developers can easily use these tools to create Ajax featured Web applications. Under such circumstances, the importance of developing Ajax features, and well-structured and easy to maintain web applications development framework is increasing.This article is based on developing process of Management Information System for Department of Science and Technology in Chongqing University. At first, in-depth research was focusd on core characteristics of Ajax technologies, as well as some open-source Ajax frameworks, then the most commonly used integrated development frameworks named SSH which is short for Struts, Spring and Hibernate was detailed studied. This paper then raise DSSH development framework, which enhance SSH with Ajax feature. The framework expands the present layer and Bussiness Logic Layer of traditional performance, thus able to add Ajax feature or construct a new web application rapidly. The usage of DSSH is then shown with in the paper, as well as comparation and test results of the integrated development framework. The integrated development framework has a certain reference value for the development Ajax featureed management information systems, or for existing J2EE-based applications to add Ajax features. |
