- Let's make the relationship between shows and networks N:N (a many-to-many relationship), i.e. each show can be associated with multiple networks, and each network has many shows). First, we need to create a junc- tion table. Do the following, preferably using only one SQL command: а. Create a junction table named show_network ,with show_id and net_id as fields. b. Make the primary key of the show_network table a composite key, made up of both fields. For syntax help, see here: https://www.w3schools.com/sgl/sql primarykey.asp Make two foreign key constraints, one for show_id and one for net_id, to reference the tables shows and networks respectively.
