Instructions: For this assignment you must submit a document file (in pdf, txt or doc format) with answers to the following questions. Consider the MOVIES relational database schema description: A movie can have 0 or more actors A movie can have 1 or more categories A movie has 1 and only one language Rating is one of these values: 'G','PG',PG-13','R','NC-17' People can comment about the movies in a webpage, and the comments are stored in the comments table. The reviewer_name is introduced by the person on each comment, so we don't have a table with "reviewers". A reviewer can create any number of comments about a movie The comments will have a score about the movie with values from 0 to 100. Note, the last update fields are going to be stored as a "timestamp". IMPORTANT: 2 entries in the same relation can have the same lastupdate, so, for example, 2 movies can have the same lastupdate value. The relations are: ACTOR (actor_id, first_name, last_name, last_update) LANGUAGE (Ilanguage_id, name, last_update) CATEGORY (category_id, name, last_update) FILM (film_id, title, description, release_year, language_id, length, rating, last_update) FILM_ACTOR(actor_id, film_id, last_update) FILM_CATEGORY (film_id, category_id, last_update) COMMENTS (review_id, film_id, reviewer_name, comment, score, last_update) 1.
