Describe a set of recommended indexes for this database. Which columns and tables should be included? Assume that read operations happen far more frequently than write operations, and that database space is unlimited. 

Movie Database Details: 

This database will support an application that tracks movies, as well as the performers and production crew for those movies (think IMDB). For each movie, the title, year of release, genre, and parental advisory rating should be stored. For each performer/crew member, first and last name should be stored, as well as date of birth and hometown.

Each performer/crew member can be related to any number of movies. The database should also track the role the individual played in the production of the movie—producer, director, screenwriter, actor, and so forth. For acting roles, the relationship should also track the name of the character portrayed. The database must allow for the same individual to perform multiple roles in the same movie.
