Todays WEB technologies have been increasingly mature and Browse / Server structure, as a new technology, has become a substitute for Client / Server structure. This paper mainly discusses how to design and implement a WEB-based Instant Messaging system which is also known as “WEB QQ”and allows users to chat in the webpages. The instant messaging system is implemented by employing both ASP.NET and SQL Server 2005 technologies under the WINDOWS platform. The system provides the functions of allowing users to chat one-to-one in the webpages and saving the chatting messages in a local text file so that users can retrieve them in the system. If friends are not online, users can also leave messages to friends. Users can also manage friends and groups such as adding, modifying and deleting friends according to the users nickname, ID, or name. Key words： WEBevelopment; B/S; Three-Tier Structure; I
