Hi guys,

I've been following the discussion about PK and its assigment since
yesterday. In my opinion it is not actually a DB feature, it is more a
conceptual feature.

Scott Ambler wrote an excelent article on mapping objects to RDBMS
where he proposes several strategies for generating and assigning
keys. You can find it here:

Personally I like the "High-low" strategy best. It works very well and
can be DB independent.
