Information on projects currently in pre-production or filming. 4. The Challenges of Crowdsourcing
Below is a design for a robust IMDb-style database, including the , SQL Code to build it, and Analytical Queries to extract valuable insights.
-- 5. Junction Table: Titles <-> People (The "Crew" table) CREATE TABLE principals ( id SERIAL PRIMARY KEY, title_id VARCHAR(20) REFERENCES titles(title_id), person_id VARCHAR(20) REFERENCES people(person_id), ordering INTEGER, -- Order of billing (1 = Star, 2 = Co-star) category VARCHAR(50), -- 'actor', 'director', 'producer' job VARCHAR(200), characters VARCHAR(500) -- Character name played );
Detailed lists of every actor, director, grip, and composer.
Here is the SQL (PostgreSQL syntax) to build this structure.
