Hmmm...  aren't all databases (relational or 
not) really tablespaces with an access method?  

I would consider DB2/400 relational.

What is the difference between an iSeries/400 
logical file and an Oracle index?  Or an Oracle 
view?  I would say none, except for 
complications on the Oracle side to keep 
everything set up for easy backup and recovery.

As long as the iSeries maintains its object-
based roots, the actual implementation of the 
database is moot.  Don't you agree?

It was not relational at the time and still 
isn't. The relational stuff is built on top of a 
basic ISAM-type database allowing split-key 
alternate indices (A.K.A. logical files).
