We learned a lot about CouchDB in this chapter. Let's quickly review
We defined CouchDB by looking at databases, documents, and the RESTful JSON API
We compared CouchDB to a traditional relational database such as MySQL
We interacted with CouchDB's RESTful JSON API, using curl statements
We created and altered documents by using Futon
We learned how to add security to a database and tested its effectiveness
Get ready! In the next chapter, we are going to start building the PHP framework that will be the platform on which we will develop in the rest of the book.
