Browser/server mode is also called B/S structure as shown
in Figure 1. It is an application of client/server extension with
the development of the Internet. In B/S mode, the user interface
is totally implemented by www browser [4]. Part of the affairs
logic is completed on front-end, but the main transaction logic
is realized on back-end server. Because the user interface is
completed by IE browser, the client need to just install browser
software, and doesn’t need the particular client-end software.
Any computer with a browser software and Internet connection
can access the system as client. Compared with client/server
mode, the greatest advantages to browser/server mode are easy
to maintain and manipulate, access to and operation on shared
data by different person in different way. So, B/S structure is
adopted in implementing of the learning platform.
