A new generation of touch information platform with flexible client or dynamic Web technology as the foundation, support figure, text, sound, and other multimedia nformation display and update, and can carry on the positive and effective interaction with the user. But from the current situation, on one hand, public information platform of touch device has broad application prospects and market value. But on the other land, among the existing developing mode and products, there still are many problems, such as poor kinds of information, poor user experience, cannot afford to complex business issues, and so on. The conflict of both sides is becoming an increasingly serious problem.To solve this problem, this thesis select RIA (Rich Internet Applications) as the main technical means.By the analysis of the characteristics and the demand of touch information platform, this thesis puts forward that the RIA technology applies technical route to touch information platform, and emphatically analyzes the heterogeneous data integration, presentation layer structure of RIA, data access efficiency, guarantee of system stability and other key problems need to be solved in the process of application, and then figures out the basic train of thought about how to solve these problems.Combined with the characteristics of business requirements,equipment and deployment of information publishing platform, this thesisproposes a development model based on WPF which makes RIA touch information platform real a system, to design the data service platform, the XBAP way to run the WPF applications, and the solutions of the whole RIA touch information platform that combinates server management system and the tenninal client system. This thesis also discussedthe key problems that may occur in the application, such as data service release, local data cache, guarantee of system stability, and etc.At last, the implementation of campus comprehensive information platform of Honghe University is introduced as a further application example. At the end, after application effect analyzation, this thesissummarizes the advantages and disadvantages of the mode of development, then puts forward the direction offurtherimprovement.
