- 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. C. Take a screenshot now and paste it here.Q9. Write an SQL statement to answer the question: 'Are there any bookings not driven by qualified drivers, i.e. driver tvpe not matching vehicle type?’ The resulting table is as follows. BOOK ID VEH_DESC YEH_TYPE 1 8728 Volvo FM12 Medium Truck Vincent Ma LGV DRIVER_MAME DRIVER_TYPE BOOK_DATE BOOK_TIME BOOK_HRS |2022/3/4 14:30 2 Q10. In view of the possible problem as per Q9, suggest a way to prevent such booking. You may consider running query to highlight this or changing the data model to prevent so. Explain your suggestion.7. Add a foreign key constraint to the shows table: the column net_id is the foreign key, referencing the column id from the networks table. Take a screenshot now and paste it here. 8. Show the structure of your table shows. Take a screenshot now and paste it here. 9. Insert the following data in your database. You may use more than one INSERT statement. title num_episodes country start end network Daniel Tiger 105 USA 2012 NULL PBS Handy Manny 113 USA 2006 2013 Disney
