Please draw an Entity-Relationship diagram for the given below MOVIE database.
The data requirements are summarized as follows:
Each movie is identified by title and year of release. Each movie has a length in minutes. Each has a production company, and each is classified under one or more genres (such as horror, action, drama, and so forth). Each movie has one or more directors and one or more actors appear in it. Each movie also has a plot outline. Finally, each movie has zero or more quotable quotes, each of which is spoken by a particular actor appearing in the movie.
Actors are identified by name and date of birth and appear in one or more movies. Each actor has a role in the movie.
Directors are also identified by name and date of birth and direct one or more movies. It is possible for a director to act in a movie (including one that he or she may also direct).
Production companies are identified by name and each has an address. A production company produces one or more movies.

- Create an ER model related to the following entities and relationships: Department, Student, Professor, Course, Section, Grade, Major. (For attributes inside each table, you only need to insert several reasonable attributes. No need to have a comprehensive list. For many-to-many relationship, you also need to insert one extra table to handle the many-to-many relationship. The final database design will have more tables than the number of entities listed above.) A given department can offer many courses. A given course can be offered by only one related department. A given course can have many related sections. A given professor can teach many sections. A given section can only be related to one course and taught by one professor.
