Polymorphism in SQL database tables?

Question

I currently have multiple tables in my database which consist of the same \'basic fields\' like:

name character varying(100),
description text,
url character         


        

Answer 1

Consider using a main basic data table with tables extending off of it with specialized information.

Ex.

basic_data
id int,
name character varying(100),
description text,
url character varying(255)


tv_series
id int,
BDID int, --foreign key to basic_data
season,
episode
airing


movies
id int,
BDID int, --foreign key to basic_data
release_data
budget
