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
