Hi all !
I've started the Scea part II examination.
I thought as the first thing to draw a component diagram.
I have some doubts on the assignment background. I have the following elements :

1. The FBN travel agents use a Cobol legacy system that accesses an IMS database

2. FBN uses TransMaster (via SSL) to process credit cards for flight purchases.

3. The IMS database will be replaced with a relational database

4. TransMaster Api won't be replaced at the moment and it's getting web enabled using XML-RPC over HTTPS.

So how does this all fit together ? this statements seems a bit contradditory.

Doubt 1:
Where does the relational database fits in this picture ? if IMS database is replaced with Oracle f.e. what happens to Cobol legacy system ? should it be replaced with EJB accessing Oracle ?

Doubt2:
The Transmaster Api will receive input from the web, but what is its output ? it will connect the web to the legacy system ? or it will persist data on the J2EE tier ?

I will be very thankful if somebody gives me an help, maybe a minimalist description on how they drew the component diagram....

Thanks
Marta

take a look at the topic "About booking airfare".
Maybe there's the answer to it.
