I just want to add some notes to all the important points people have
flashed till now on the list.
1. If a database works good for some time, this doesn't mean it'll be so
forever.
Some points must be checked out before making a decision:
a) how many records a table can handle.
b) the length of the index file. i.e. the number of bytes permitted in
every record.
c) how many indexes can be opened and working at the same time.
d) how many requests can be made SIMULTANIOUSLY against a table or a
number of tables.
e) Response time with complex requests.
f) the need to upgrade and/or link this database to others in the
future.
g) The ability to handle pictures and/or movies (if needed) and in which
format, to what limited size, and how the response will be.
Usually the salesmen give attractive but inaccurate words regarding
these questions. You must refer to the manuals and/or discussion groups
of the products to get the exact answers.
A failing in an answer of a question can result in a higher cost in the
future.

I hope this helps.

Osman.
