MongoDB is a database. However, unlike conventional relational databases that are based on well defined schema and use SQL as the primary interface to manage the data, MongoDB instead uses document based storage.
The storage uses a format known as BSON, which is a modified form of JSON. This makes the stored documents very flexible and lightweight. It also makes it easy to adjust what is contained in any document without any significant impact to the other documents in a collection (a collection in MongoDB is like a table in a relational database).
In this short video I show you how to install and begin using MongoDB. The video is HD, so be sure to watch it full screen to get all the details.
When you’re done with this, go have a look at how to improve MongoDB’s reliability using replica sets.
