Design Of E-mail Group Sending System And Its Application In Implementation Of Digital Campus Community

E-mail group sending is a kind of communication measure that comes of single E-mail sending. In present, it has become a kind of standard E-mail service, having strong technology, a great number of users, and being widely used in many domains. In general, a E-mail group sending system's technology core is POP3 E-mail processing that based on TCP/IP, and it usually works in a E-mail processing system that based on Web pages, users receive service from Web pages by using browser. This kind of working measure is the most popular E-mail processing service measure, and it is just the measure that used to design the system discussed in this thesis.This thesis's research object is the common design ways and means, its system structure is Browser/Server, and its implementation measure is JSP+JavaBean mode. At last, this thesis provides an overall description of design and implementation of an application system that using E-mail group sending function, with using a digital community system as an instance.The thesis firstly introduces some background knowledge, including JavaMail / JAF, these technologies are the core of E-mail processing; all the protocols those E-mail processing bases on; and the standard E-mail processing functions. Secondly, it classify the major measures those used to deign E-mail group sending system, and generalize an implementation model for deign E-mail group sending system. At last, refer to the model, it elaborate the design and implementation of digital campus community system, this system uses E-mail group sending fuction. In the part of system design, the whole scheme is proposed on the basis of system anlysis; in particular, the function and database design of the system are intensively discussed. In the part of system implementation, methods are introduced about how to implement each module of the system, and key technologies being elaborated. Finally, the thesis makes an objective overall of the system by carrying out a system testing and observing the result of system running.
