As we saw, Couchbase is an extremely flexible and scalable database. It offers a set of complimentary key/value and document features not found in any other database. In the next few chapters, we'll explore these features in detail. You will learn how and when to use them.

We also set up our single-node Couchbase cluster. Our default and sample buckets were created. We explored the Couchbase Console and discussed cluster architecture. With this knowledge in hand, you're ready to dig into application development with Couchbase.

If you've used either Memcached or CouchDB, you'll find the next three chapters to be somewhat familiar. In the next chapter, we're going to dig deep into Couchbase's key/value API. As we'll see, at first it will look a lot like Memcached, but it'll quickly go above and beyond.
