Well certainly you have have two records with the same ID, but only if
there is more than a single file in play.  I can have record X in both
file A and file B, but I cannot have a record with a key of X twice in
file A without some file corruption.

There is uniqueness within a single file, but not necessarily "global
uniqueness".  Then again, without some funky programming no other
databases have globally unique identifiers either.

Subject: [U2] Unique Ids

I just came out of a meeting where it was stated that MV databases
allow non-unique keys.

Now I have been working in the VM world since 1983 and although I can
remember a time when some of the implementations had 'problems' with
hash and specific data in keys .. i can not think of a time when MV
tables allowed non-unique keys.

'Say it aint so Joe' .. 

If anyone knows of any implementation which specifically allows
non-unique ids .. please let me know .. show me the light.  Have I be
in the back room eating twinkies too long?

thanks
