Design And Research Of The E-mail Based On RIA

With the rapid development of network, E-mail has become the most popular application on the Internet. Everyone may have one or several E-mail boxes. Thus common letters have been gradually replaced by the E-mail, and which is become the main way of communication. An E-mail system which is more convenient and quicker has become users' demand. at the same time, making an E-mail system which can meet different people's requirements is also become a goal of designer.The traditional networking program is developed due to the model of the page server to transfer data before the appearing of the RIA, and the presentation layer of the networking program which is install on the page of HTML.so the system which is developed due to the traditional networking program that can't meet users' more and multidirectional demand, then the RIA is developed to solve this problem. Flexibility of the Web application and interactive experience of desktop applications are combined by RIA, what's more, it can offer the multimedia communications. the rich function of RIA is just a theory model on the web 2.0. Based on this model, this paper used the method of realization of RIA based on Flex to implement Email module, this module can offer the rich operation, besides, it can finish complex applications to meet users' more and multidirectional experience demand and ensure the timely and dynamic.In this paper, the flex technology, the database technology and knowledge of the RIA are introduced in the firstly, then the structural, the functioning parts, and the data model of this E-mail module were detailed analysed.
