My question is just about that.

I received a lot of opinions about conversion from applications based on
indexed-sequential to relational database which are saying it represents
a huge structural transformation, because of the very different
philosophies (for example about how to normalize, how to deal with cobol
redefines or occurs clauses, etc,...).

I think there are been a lot of work done on that in the mainframe
environments, and a lot of commercial proposals. It seems they are
dealing with non trivial issues.

But perhaps something can be done and there are innovative methods for
that. I have not a definitive opinion on that. And because of what you
have told, I was a little bit curious.
