The rating can be different in the different versions of the same movie - So Jaws 1975 can be R and Jaws 2019 can be PG-13 - A movie can have only one Genre - Example, Alien is just sci-fi - A movie can not have different versions in the same year. . Example, we can't have two Jaws in 1975 - An actor can be in more than a movie the same year . Example: Charlton Heston can be in Ben Hur in 1959 and in Harry Potter in 1959 too (I know...I know... it is just an example) There is not any Studio with the headquarters in more than one city, but we can have 2 studios in the same city. . So, Universal can not be in Hollywood and in any other place, and MGM can be in Hollywood too. . An actor can work with more than one studio. . Example: Bill Murray can work in a Columbia's Movie and for MGM's movie QUESTIONS A, Use: Title - T, Year - Y, Length - L, Genre - G, Studio - S, City_Studio-C, Actor Rating R 3) a- Is Movie in 1NF?
