In this chapter, you learned some new PHP functions that allow you to interface with a MySQL database server. Using these functions, you built your first database-driven Website, which published the jokes database online, and allowed visitors to add jokes of their own to it.
In "Relational Database Design", we go back to the MySQL command line. We'll learn how to use relational database principles and advanced SQL queries to represent more complex types of information, and give our visitors credit for the jokes they add!
