Choose six recent popular movies. Ask at least five people that you know (friends, family, classmates, imaginary friends) to rate each of these movie that they have seen on a scale of 1 to 5. Take the results (observations) and store them in a SQL database. Load the information into an R dataframe.

Your deliverables should include your SQL scripts and your R Markdown code, posted to GitHub.

SQL Code: DROP DATABASE IF EXISTS movie; CREATE database movie;

CREATE TABLE users (userID int not null auto_increment, firstname varchar(20), lastname varchar(20), primary key (userID));

INSERT INTO users (firstname, lastname) VALUES (‘Fawad’,‘Younus’), (‘Saad’,‘Younus’), (‘Mariam’,‘Shabbir’), (‘Wajidul’,‘Hussain’), (‘Atib’,‘Ali’);

CREATE TABLE movies ( movieID int not null auto_increment, title varchar (30), genre varchar(20), RottenTom float, primary key (movieID));

INSERT INTO movies (title, genre, RottenTom) VALUES (‘Crazy Rich Asians’,‘Action’,9.3), (‘The Meg’,‘Action’,4.6), (‘Mission Impossible’,‘Action’,9.7), (‘Christopher Robin’,‘Family’,7.0), (‘The Nun’,‘Horror’,2.8), (‘Incredibles 2’,‘Animation’,9.4);

CREATE TABLE reviews( userID int, movieID int, userrating int);

INSERT INTO reviews (userID, movieID, userrating) VALUES (1,1,4),(1,2,4),(1,3,3),(1,4,4),(1,5,4),(1,6,5), (2,1,3),(2,2,3),(2,3,2),(2,4,5),(2,5,5),(2,6,3), (3,1,5),(3,2,5),(3,3,5),(3,4,4),(3,5,5),(3,6,3), (4,1,4),(4,2,3),(4,3,2),(4,4,2),(4,5,4),(4,6,3), (5,1,5),(5,2,3),(5,3,3),(5,4,4),(5,5,4),(5,6,3);

SELECT users.firstname, users.lastname, movies.title, movies.genre, movies.RottenTom, reviews.userrating from reviews JOIN users on users.userID = reviews.userID JOIN movies on reviews.movieID = movies.movieID ORDER BY title;
