Question
Chapter 17, Problem 17.5E
Program Plan Intro
Fat client:
It is also called as thick client. It is nothing but a software that implements its own characteristics. It connects to servers but it functions greatly even when disconnected.
Example: Games
Thin client:
It is not like fat client because, here, only the UI is presented on the client system and all other functions are carried out on the server.
Example: Web browser

A Banking System provides users with several services:
(i) to check their accounts to see recent transactions and balances;
(ii) to pay bills online;
(iii) to buy and sell investments.
All of these services require a secure log-in. If the system crashes or the network connection fails during a transaction, it is essential that all the financial data is left in a consistent state.
b. Show the architecture of the product that you intend to build. Justify your choice of architecture.
You have been asked to design a secure system that requires strong authentication and authorization. The system must be designed so that communications between parts of the system cannot be intercepted and read by an attacker. Suggest the most appropriate clientserver architecture for this system and, giving the reasons for your answer, propose how functionality should be distributed between the client and the server systems.
In a client-server architecture with two tiers, I can't see how a malfunction of catastrophic proportions might occur. How can we solve this problem using a client-server architecture that has several layers?
