Are they married to each other?</li> <li>Singers: What songs did they write? Where are they from?</li> <li>Authors: What books did they write?</li> <li>Fictional characters: How are they related to other characters? What books do they show up in?</li> </ul> project https://www.khanacademy.org/computing/computer-programming/sql/relational-queries-in-sql/a/more-efficient-sql-with-query-planning-and-optimization 2021-04-29T07:57:01Z More efficient SQL with query planning and optimization article
