UML

##Synopsis This is the model section. This section describes the models use for the database on SWEetMusic. There is three models on the Unified Modeling Language(UML) which are Artist, Album, Track. The UML has 2 many to many relationship and one to many relationship. The first many to many relationship is between Artist and Albums because an Album can be release by many Artist and Artist can release many Albums. The second many to many relationship is between Artist and Tracks because an Artist can sing many Tracks and Tracks can be song by many Artist. The last relationship would be the one to many relationship between Album and Tracks because an Album could contain many Tracks but a Track could only be in one Album.

1. Artist: Contains information about the Artist: name, number of albums, recent album, etc
2. Album: Contains information about the Album: name, date it was released, etc
