A couple of reasons. The database is currently around 1500 records and
they're adding to it everyday. One patient could rent a few pieces of
equipment on each visit and that same patient could have more than 1 visit.
I would like to have that patient entered just once in the database and then
use a separate table to track all the rented equipment. I don't want to
keep duplicating the patient info. Also, more than 1 person enters data into
the database. With a patient table there's less of a chance of duplicate
patients with misspellings. They will search on a patient name before adding
it as new.
I want to create a form with a subform so when they search on a patient, all
the patient's transactions will appear. This way it will be easier when
they need to update a transaction.
Does this sound like the right reasons to separate the table? Thanks for
your help.

Hi Suzanne,
Why do you want to do this? Are you talking about a lot of records? A simple
query should give you a table with non duplicated patients if you just want
a list of unique names.
