Migrating from RMS to Oracle

[Kevin Erne]

Sorry to be so blunt, but you seem to be asking some very basic questions
about a fairly major migration. Do you have no PowerHouse/Oracle experts
on site? 
I can think of lots of other issues that you may need to address such as
transaction handling within QUICK/QTP plus the data placement/sizing issues
within the Oracle database.
If you are based in the US or UK , I would suggest getting in a contractor/consultant
with PowerHouse and Oracle experience - there are plenty available!!

PS. Oracle 9i does allow you to 'nest' a table  within another table - but
for a true relational model you would need to create a separate table ofr
each coded record structure
