Summary
Understanding the WordPress database is the key to building successful web applications. Throughout this chapter, we looked at the role of existing tables and the need for custom database tables through practical scenarios.
Database querying techniques and limitations were introduced with the necessary examples. By now, you should have a clear understanding of choosing the right type of tables for your next project. We had to go in a theoretical approach with practical scenarios to learn the basics of database design and implementation inside WordPress.
The real excitement begins in the next chapter where we start the development of our main modules in web applications using the building blocks of WordPress, so stay tuned.
