I have two tables in a many to many relationship.

Users
====
id: int
name: string

Raw Data:
====
id: int
latitude: double
longitude: double

Raw Data Users
==========
user_id: int
raw_data_id: int
selected: boolean

I was wondering which method would be the best way to handle the many to many mapping such that I could get the select value from the raw data user table while inspecting the raw data class? I'll would also like to do an outer join on the linking table to get the specific "selected" values in relation to a single user.

TIA
