Req. Composer Installation - With DB2 Express-C or Cloud AMI

Hello :

I wish to try Req. Composer however, I do not have a DB2 version on my local PC. I can install DB2 Express-C (Free) on my PC but am not sure if that will work with Req. Composer. The software requirements for Req. Composer seem to be DB2 Express not DB2 Express-C.

A) So will Req. Composer work with DB2 Express-C?

Also, I was wondering if it won't then could I rent a DB2 Express AMI at Amazon Web Services and have Req. Composer work off of that.

B) Will that work?

Any help will be appreciated.

Thanks,
Pawan.
