Well Nico, you're the one who have to decide whether the suggestions are
good or not!

I'd recommend you to be conservative about adding fields - that is, don't
implement every idea from every user. Try to get user A talk to user B so
that the three of you can agree in what ideas are worth implementing. It is
not uncommon for users to come up with what they think is a good idea only
to find out a week later that they had forgotten to take something into
consideration and really wanted some different information.

As for splitting a table, there is normally no need for doing this only
because of the number of fields in a table. Rather, think about the data.
Repeating groups etc. are of course worth splitting into separate tables
(normalisation theory) and you may consider separate tables for fields
irrelevant for most records. In your example, I wouldn't bother to have a
separate CUST_DELIV table if the eight fields typically were filled for
most customers - unless you wanted to record some history so that you knew
the delivery information at any given time (companies may move or have
several delivery addresses).

But I must admit that 50 fields sounds a lot for a customer table - does
all fields really contain different information?

HTH,
