How to get a user list that belongs to a team area

Hi,
I'm trying to find out if anyone has written a script and query that allows an RTC admin to get a list of users and their email address that belongs to a particular team area(s) and or project. The reason for asking, I've gotten requests from project owners who wants an email to be sent out to users that belongs to a particular team area to validate if they still require access for audit purposes.
The scripting part is easy, just not so for querying the database, since I have not seen any documentation of the database.

Any help is very much appreciated. Thanks.
