1.web is b/s, Mobile is C/s
2. Performance of the system:
b/S advantage is the remote browsing and information collection more flexible, anytime, anywhere, as long as the browser can use the Internet
But the client can only complete the browsing, query, data input and other simple work, most of the server bear, the burden will be very heavy, C/S client and server can handle the task, although the client requirements are high, but can alleviate the pressure of the server, and because the client uses the browser, Is the information published on the Internet is mainly transmitted in HTML format, most of the other formats with attachments, and HTML format files are not easy to edit and modify, to file management inconvenience
3. System upgrade and Maintenance
c/S system parts of the module changes, it is related to the changes of other modules, is the system upgrade cost is relatively large, compared with B/s, the client is easier, as long as the internet on OK, that is, development and maintenance are almost centralized in the server side, when the enterprise to upgrade the network application, only need to update the server, This reduces the cost of offsite user maintenance and upgrades.
4.C/S Advantages and Disadvantages

b The interface is beautiful in various forms, can meet the customer's own individual needs
C/S architecture has a strong ability to deal with things, can achieve complex business processes
Disadvantages
A requires a dedicated client installation program, weak distribution, for a wide range of users who do not have network conditions, can not achieve rapid deployment installation and configuration
b poor compatibility for different development tools, has a large limitation, if the use of different development tools, need to rewrite the program
C Development Cost is high, need to mobile professional level of technical personnel to complete
b/S
Advantages
A distribution characteristics, can be any time to query, browse and other business
B Business expansion is simple. Increase server functionality by adding Web pages
C Maintenance Simple aspect, the order changes the webpage, can realize the synchronization update
