Summary
The article discusses the challenges of representing hierarchical data from movie databases in SQL relational structures. It explains that movie data (directors, genres, actors, characters) has inherent hierarchical relationships that don't fit well into flat relational tables. The article highlights how different database pages organize the same data in different hierarchical orders (movie→actors vs actor→movies), making direct hierarchical storage problematic for SQL databases.

The order of the hierarchy isn't the same on both pages
So you can't just directly store the hierarchy in your database
