In this assignment, you will query a database of movies, actors/actresses, and directors. This data is a subset of the Internet Movie Database and is used in compliance with their terms and conditions.
To load this database into PostgreSQL:
pgAdmin by clicking on Databases in the left pane, and then selecting Edit -> New Object -> New Database... from the top menu. Name the new database imdb.imdb in the list of databases in the left pane of pgAdmin. Click on it, and then select Tools -> Restore... from the top menu. Find the file imdb.backup and restore it.You should now have four tables in the the imdb database: cast_info, movies, people, and role_type.
The movies table contains information about some 1600 Hollywood movies. All feature-length movies up until late 2013 with at least 50,000 ratings on IMDB.com are included. The title, production year, rating, and number of votes are included in this table.
The people table contains information about all of the actors, actresses and directors that appeared in the movies in the movies table. The names and gender of these people are included.
The role_type table is a small lookup table that relates role_ids to roles. This subset of the IMDB database contains only actors, actresses, and directors.
The cast_info table is a lookup table that relates people to the roles they played in certain movies. Each row in the cast_info table is an assignment of one person to one role in one movie. Obviously, a single person can play multiple roles in a single movie, or perform in many movies.
