Missing your text editor with today’s database fest? Why not try using your freshly-expanded database structure by updating the joke list example to display theauthor’s name (maybe even linked to their email address) next to each joke? Hint:the last SELECT query we looked at in the previous video will come in handy.

That’s all for Lesson 8! Next up is Database Design: Complex Relationships.
