Besides the functions of receive and deliver mails, the mail system offers a few more features. However, people do not really use these flashy functions, especially for those who know few about computers. Therefore, it would be of great users’ convenience to develop a simple, practical and user-friendly email system, which integrates sending, receiving, and management functions. The email system is based on internet, using the SQL Server 2005 database ASP.NET technology. The system is one software system that combines the functions of sending, receiving, and managing emails. Its main features include sending and replying emails. Users can send mails on work and greetings, receive the mails, and manage the emails. Guided by software engineering theory, the system design concept is discussed in the instruction book. The main task of the various stages of system development is analyzed. The system principle and solutions of the various functional modules are described. The system development process is summarized in the end.
