Good job ian..
I have couple of questions though..
You need to integrate your application with a mainframe system but don't have any access to the mainframes code. What is the best technique for this?
(A) It can't be done. (B) Use a screen scraper. (C) Re-write the main frame using Java. (D) Write a Java front end then use CORBA to communicate with the mainframe
Ans: (B) ... why not (D)?

What are the weaknesses of two-tier architecture with regards to the following areas?
(A) Fat Clients (B) Thin Clients
(C) Scalability (D) Potential Network bottlenecks
Tightly coupled/brittle architecture has
main weakness like Fatclient(mix of presentation and business logic) and scalability issues. But i dont see network bottlenecks. Can any one explain it to me how (D)is also a valid anwer?
