This is one example of Oscar awards, which is to be supported by the ER diagram.

Oscar prizes could be given to outstanding production company for the movies they produced, or to stars for outstanding performance in the movies. Some companies or individual could win more than one Oscar for the movie.

Nicholas Cage has won two Oscars for his performance in “National Treasure” and the stars of “Batman” has won one Oscar each. Paramount Pictures has won one Oscar for outstanding production of the “Last Airbender” and so has Summit Entertainment for “Eclipse”.
