In this lab, you will be using the Sakila database of movie rentals. You can follow the steps listed here to get the data locally: Sakila sample database - installation. You can work with two sql query files - sakila-schema.sql (creates the schema) + sakila-data.sql which inserts the data.
The ERD is pictured below - not all tables are shown, but many of the key fields you will be using are visible:
- Use sakila database.
- Get all the data from tables
actor,filmandcustomer. - Get film titles.
- Get unique list of film languages under the alias
