The Design and Implementation of A Java-Based Internet Communication System
Abstract: Communication on Internet is very popular and crucial in people¡¯s live. Using the network communication technology, we can chat with our friends at any time. For instance, we can chat or communicate with friends and our company by some chatting tools; we even can buy everything we want on Internet. This system is designed based on computer networking technology and some relative knowledge, using JAVA and SQL SERVER 2,000 database system as tools to develop. This implementation is based on C/S (Client/Server) model. The model can be divided into three levels: Databases level¡¢Server level¡¢Client level. According to this idea, we can distribute the task into two parts: the client and the server. The benefit is that the cost is cut down. From the needs of easy operation, beautiful and vivid interface and practical application, we can design a system which functions is including user registering, user login, adding friend, deleting friend, chatting and so on. This paper introduces the background of the development, the functions demanded and the process of design. What¡¯s more, the paper focuses on the design principles¡¢implementation details¡¢the key techniques and the solutions.
Keywords: Web application; Java; C/S model; Socket.
