Abstract

Along with science's and technology's unceasing enhancement, the computer science is mature day after day, its formidable function had known profoundly for the people, it entered the human society each domain and is playing more and more vital role. Chats at present has become one way which the people exchange mutually, with E-mail, the telephone compares, chats the service to have timeliness and the validity.

Front end this chats the tool to take using C++ the application development kit, Access takes the backstage the database, uses the client side/server's model construction, the structure vigorously and healthily nimble, in aspects and so on data processing, man-machine contact surface, data communication, system maintenance has the function comprehensively, practical and so on characteristics.

Including the server end and the client side two modules, the client side carries on the correspondence through the server end. This software uses the multithreading technical support multiuser operation, and used the correlation technique to carry on the optimization, sped up the writing transmission speed.

Key words: C++, Access, Chats the tool
