Study And Application Of Web Returns To Desktop Trend

Along with the rapid development of the Web technology, the functionality of web application and user experience have been as good as the traditional desktop application. At the same time, with the appearance and popularization of platforms like Adobe AIR and Curl Nitro, more and more desktop applications now can be realized with the Web development technology. Web application with desktop application characteristics, as well as the desktop application realized with Web development technology, the combination of Web technology and desktop technology brings the birth of "Web returns to desktop" technology trend. Under this technical background, this paper describes the design and implementation of a "prepayment metering management system based on Web technologies", by which we can understand and explain " Web returns to desktop" trend.This paper analyzes the problems in the current prepayment metering management system and introduces a new system, including the design ideas, the main functionalities, the self-help mode and the key development technologies. With the ideas of platform-based design, the system uses the hierarchical design, which improves the reusability of the platform layer, and reduces the coupling between the layers. With the application of industrial remote monitoring technology, the system improves the real-time and the reliability of the operation. The use of Web Services makes the integration of the third party application possible. And the use of AJAX, SVG and XHTML technologies realized the desktop application user experience.Also, this paper explores a new mode of developing desktop applications with the Web technologies, and describes its advances and requirements. Based on this mode, a self-help client application is designed and realized which then is packaged, distributed and deployed and finally runs on desktop environment. This indeed verifies the feasibility of this mode and the application's capability of integrating it with desktop.This system has been used and run well in several universities and markets.From the points of building Web application with desktop characteristics and realization of desktop application with Web development technology, this paper illustrates the trend of Web returns to desktop. It is consistent with the Internet's development direction, and will integrate the advantages of web application and desktop application, and thus causes the appearance of a new type of software application, which will change the software development mode.
