Mini- Case #1

a. Classify the two alternatives in terms of what type of application architecture they use.

The first option: the clients will download special tool for their computer is classify under the Client Based Architecture. The second option, the program running on the sever while the client use their browser is classify under the Two Tier Client - Server Architecture

b. Outline the pros and cons of the two alternatives and make a recommendation to Fred about which is better.

Client-based pros:

Inexpensive to implement

Allows hardware of different makes to function together

Client-based cons:

Data traffic must be sent and received between client and host

Performance of overall network can be affected because of the amount of data sent and received

Two-tier Client-server pros:

Better performance because processing is distributed to multiple machines

Using a web browser as the client for this architecture means no deployment is necessary. Presentation is changed on the server and is immediately reflected on all clients accessing the server.

Two-tier Client-server cons:

A key concern with the 2-tier model is scalability. Application performance can be expected to degrade rapidly when the number of concurrent users reaches a threshold between a few hundred and one thousand users.

 Application changes have to be distributed to each client. When there are a large number of users, this entails considerable administrative overhead

I would recommend Two-tier client based architecture because it would be more readily adaptable as technology changes, which will ultimately save both time and money.
