Question

Ok SO, I have a user table and want to define groups of users together. The best solution I have for this is to create three database tables as follows:

UserTable

user_id
user_name

UserGroupLink

group_id
member_id

GroupInfo

group_id
group_name

This method keeps the member and group information separate. This is just my way of thinking. Is there a better way to do this? Also, what is a good naming convention for tables that link two other tables?

Answer 1

Looks, good, I would go with:

Group
-----
GroupID (PK)
Name
CreatedDate

GroupUser
---------
GroupUserID (PK)
GroupID (FK)
UserID (FK)
CreatedDate

User
----
UserID (PK)
Firstname
Lastname
CreatedDate
