Hello, I'm new to DB2.

I want to design and implement a new database in DB2 for AS/400 (VR5M2).

I'm not familiar with the tools for DB2 to develop such DB and applications, and after reading some material in the IBM site, I'm even more confused.

DB design:
Which tool is there to design and implement databse for DB2 (design the logical DB and then the tool generate the code for the Physical).

App design:
I use to develop in C#, and I would like to keep it in my application that would work with DB2 for the AS/400 - what tool would be best for that (from Windows Env.)?

Thanks in advance,
