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.

Actors are identified by name and date of birth and appear in one or more movies. Each actor has a role in the movie.

It is possible for a directorto act in a movie (ncluding one that he or she may also diec Production companies are identified by name and each has an address. A production company produces one or more movies. Design an entity-relationship diagram for the movie database and enter the design using a data modeling tool such as ERwin or Rational Rose
