Hi,

This question would be a bit childish, I have three tables, users, usergroups and contacts. In my system, the end user can create a contact and subsequently he\she may define the visibility of the contact by setting only for that user, or for a set of users or a set of usergroups. So I am wondering, how my database design would be, it should be many to many between users and contacts or many to many between usergroups and contacts. Definitely there is a one to many relationship between users and usergroups.

Thanks Thurein
