The following attributes represent data about a movie copy at a video rental store. Each movie is identified by a movie number and has a title and information about the director and the studio that produced the movie. Each movie has one or several characters, and there is exactly one actor playing the role of each of the characters (but one actor can play multiple roles in each of the movies). A video store has multiple copies of the same movie, and the store differentiates copies with a movie copy number, which is unique within a single movie but not unique between different movies. Each movie copy has a rental status and return date; in addition, each copy has a type (VHS, DVD, or Bluray). The rental price depends on the movie and the copy type, but the price is the same for all copies of the same type. The attributes are as follows:
