Music Collection data model


See data model below. The tables in the orange box represents already existing tables that I will be grabbing data from. Blue tables are join tables, and the green ones are regular tables. Further down you will also find a list of tables and a brief description of each table.

Each moderator tuple corresponds to a tuple in the collection_info table. collection_info holds information about a user's collection. Through the join table collection_watch_artist_join collection_info knows which artists the user want to see missing releases from.

The collection_has_release_join and collection_ignore_release_join is for knowing which releases the user have in his/her collection, and which releases to ignore. collection_discography_artist_join is for knowing which artists the user want to view missing releases from.

Note that not all functionality facilitated by the data model is must have functionality - things that I have to implement to pass this Google Summer of Code project.
