I am with you as far as terminology is concerned. Not necessarily as far as
the value of concepts is concerned.
I did go through a brief period when I tried to talk to non technical people
in terms of tables in 1NF. I quickly gave up, especially when I noted that
you can talk to people about data in an ER model without ever getting
involved in normalization.
There are people for whom an invoice is an invoice header, and a bunch of
invoice items. Talking to these people about repeating groups, subentities,
or 1NF is a complete waste of their time and mine. ER is my way of avoiding
that pitfall. Your way is different.
The good news is that converting an ER model into an SQL model is so straightforward that an engine like DA can do it automatically. And even if you don't have a tool like DA, it's still a simple exercise. Received on Sat Oct 23 2004 - 19:18:46 CEST
