The C/S (Client/Server) structure [13] applied to
traditional management information system uses the answer
mode of “request/response”. The client initiates the
“request” while users need visiting server. The server
responds and executes corresponding services then returns
the client relevant execution results after receiving the
“request”.
In C/S structure, clients connect server directly. The
response mode of “request/response” needs no processing
step so that it reduces data loads and speeds up system
response time. But C/S structure can just apply to local area
net (LAN). The special client development tools reduce
system generality, expansibility and client’s program
compatibility; increase promoting difficulty and operation
cost; lead to weaker system distribution. So it couldn’t
achieve rapid deployment and configuration; and is difficult
to realize the dynamic release of information.
Web-based B/S (Browser/Server) architecture could
manage the network system easily just needing installing a
browser in the client. Administrators achieve management
functions for the managed network on client browser of any
computer linking to internet with web-based network’s
strong distribution. Meanwhile it could extend the
management functions of network only by increasing web
pages that the costs of maintenance and administration
significantly reduce. Through the web server connecting
database, it could carry out data query, update and displaying
in the web pages. That greatly enhances system’s interactive
ability; achieves the dynamic release only by updating some
records and fields in the database on the GUI (Graphic User
Interface).
