Re: Help with phoneBook db design

you have people. first name, last name, address, and identity, i'll
call "peopleid."
you have a "phone number.". the actual number, and something i'll call
"phoneid."

you have a cross reference table of "assignedphone." in that table
will be AssignedID, peopleid, phoneid, adn perhaps startdates,
enddates, etc.

You will have a different cross reference table of "distribution."
DistributionID, and another peopleID for the "owner of the distribution
list." Here it gets a little interesting. If your distribution list is
a list of phone numbers, then include PhoneID's. If your distribution
list is a list of people, then include teh peopleID's. For the latter
case, use the assignedphone to go get the assigned phones, then off to
the phonenumbers to get the actual numbers.

Start there. When you have mastered the logic, then grow the app to
include the second order distribution lists. this is enough to get you
started though.
