ERD Movies We would like to make a system to store information about movies: different releases and versions, actors and directors. First we would like to keep track of how many days an actor worked on a certain movie. An actor obviously has a name, a first name and date of birth. Also we would like to know the name and first name of the person who directed the movie, and which salary he/she received. For movies, we would like to track in which year a title was released and to which genre it belongs. We would like to be able to generate a list of additional versions of a movie (like Lord of the Rings Extended Edition, or a Directo's Cut) and when they were released. It is possible that, usually years after the original, a remake is being made of a film. We want to keep track of that too. These are new films in their own respect, not additional versions. We do want to be able to ask which original film they are a remake of, and vice versa: which remakes exist of an original film. Create a full ERD. You may make assumptions for any missing information (for example, if there are no suitable primary keys).
