As the Database world evolves one of the rapidly developing space in Databases is NoSQL databases. There are a variety of implementations available. I had blogged about NoSQL Databases in an earlier blog post. Here is one I would like to share with you all, it is a database called MongoDB. There is a very detailed and excellent article post on MongoDB architecture by Ricky Ho. It is very well written and the differences between Relational and NoSQL have been highlighted.
