In this lab, you will be using the Sakila database of movie rentals. You have been using this database for a couple labs already, but if you need to get the data again, refer to the official installation link.
The database is structured as follows:
- Which last names are not repeated?
- Which last names appear more than once?
- Rentals by employee.
- Films by year.
- Films by rating.
- Mean length by rating.
- Which kind of movies (rating) have a mean duration of more than two hours?
- List movies and add information of average duration for their rating and original language.
- Which rentals are longer than expected?
