In case you weren't able to make it to the latest webcast from the php|architect TEK-X series - Kristina Chodorow on MongoDB - you can catch it all here in the recording of the event.
MongoDB is part of a new wave of persistent storage engines that make up the NoSQL movement. The most popular websites in the world are switching to or already use non-relational databases. Why? Scalability. This session will cover why, when, and how to use MongoDB: a fast, stable, easy-to-learn document database.
You can find out more about MongoDB from its website and more about the remaining TEK-X webcast series (only two left!) on the TEK-X webcast series page.
