Summary

In this chapter, you learned about MongoDB, a document database that is very popular amongst NoSQL databases. Documents stored in the database are basically nothing more than JSON objects. They can be grouped in collections, the equivalent of tables in RDBMS.

Using the MongoDB shell, we can populate databases and collections from the command line. From within web applications, we can access a MongoDB database on the server using PHP. This is really easy because JSON objects can be written as associative arrays.

In the last few chapters, there was a lot of sample code and I promised you a textbook so you can learn away from the computer. In the next chapter, there will be a lot more reading to do.

The newest trends in web development are being discussed, triggered by the totally different way people are using the Web compared to just a couple of years ago. We are going to focus a little more on how your website looks and a little less on how it works.
