This is a beginner question:
A user can belong to many groups, and a group can contain many users.
Let's say the two tables look something like this:
user_id user_name user_email
group_id group_title group_description
Where and how do I store all of the users which belong to a group and all the groups a user belongs to?
I can't imagine the groups table having a users field which contains comma separated user IDs being an acceptable solution. I think I get the basic concept of relational databases, but I'm not sure of the implementation. I get the one-to-one relationship, but I'm struggling with one-to-many. Is what I'm dealing with in this example two separate one-to-many relationships?
