Movie Catalog Database Schema
Today we are going to create a database schema for a movie catalog. It could be used for a web-site like IMDB or a desktop software to catalog movies.
Our main table to store information about movies is the movies
table.
This table holds the main aspects of the movie like the following:
- Title of the movie
- Release date
- Run time length of the movie as minutes
- IMDB id of the movie
- MPA Rating of the movie (G, PG, PG-13, R, NC-17)
This table has a reference to languages
table which holds the language of the movie.
Next we have the plots
, languages
and genres
tables. These are all colored with the same color because they hold the detail information about a movie.
The plots
table has a many-to-one connection to the movies
table and one-to-one connection to the languages
table. This is because a movie can have multiple plots in different languages. The languages
table is referenced by the movies
table as we have mentioned above. This is for the language of the movie it self.
We have a many-to-many connection between movies
and genres
tables. This is because a movie could have multiple genres
. There is a movie_genres
table to be able to establish the many-to-many connection.
There are many ways to represent people associated with a movie. We could have separate tables for directors, producers, actors and actresses and these tables could hold that persons details. However we chose to create a single people
table to represent any person and have various join-tables to represent the association of the specific person to the movie.
Any person who is not an actor/actress is represented through a record in the people
table and a connection through directors or producers to the movies
table. Depending on our needs, we could add writers
, executive_producers
, production_managers
and many other similar tables with the same structure as producers
and directors
tables. A foreign key for people
and a foreign key for movies
is all that is needed.
To represent the actors in the database, we will do something different than directors
and producers
. An actor plays a character in a movie. Sometimes a character is played by different actors. For example in X-Men: First Class (2011), James McAvoy plays the 30 year old Charles Xavier role and Laurence Belcher plays the young Xavier role. It is also possible that the same character is portrayed in different movies. Like in the other movies in the series, where Xavier is portrayed by Patrick Stewart.
To be able to model this scenario where a character is not specifically tied to a movie, we have characters
table which is associated with the movies
table through a join-table.
Note: The correct plural form of person is people, although you can name the people
table persons
if you want to keep the naming consistent.
Finally we have the awards
table. This table would hold the list of awards (94th Academy Awards, 79th Golden Globe Awards, Palme dβOr etc). It has name and year fields of the award, however we could add, ceremony_date
, ceremony_location
, presenter
and many other fields if we need them.
The awards
table is associated with the movies
table through the movie_awards
table. The category
field would hold the name of the award (Best Picture, Best Actor, Best Supporting Actress etc). won_awards
field is a boolean field that represents if the award is won or if it is just a nomination.
We came to the end of our tutorial. You can open this sample movie catalog schema in dbmodeller and use it in your own projects.
