Flexing NoSQL: MongoDB in review
The <a href="http://www.infoworld.com/d/data-explosion/no-sql-new-databases-new-applications-400">NoSQL movement</a> has spawned a slew of alternative data stores, all of which attempt to fill voids left by traditional relational database implementations. But while it's easy to fit the various relational databases (MySQL, Oracle, DB2, and so on) under a single categorical umbrella, the NoSQL world is much more diverse, and the NoSQL label is too general. NoSQL data stores such as MongoDB and Cassandra are so vastly different from each other that apples-to-apples comparisons are practically impossible. Thus, within the world of NoSQL, there are subcategories such as key-value stores, graph databases, and document-oriented stores.
