This video below provides an overview of the core concepts behind "MongoDB," the popular noSQL document-oriented database.
In the video, Jared Rosoff covers the basics of Mongo and then explains the purpose and architecture of MongoDB replica sets (for scalable read operations) as well as MongoDB's approach to sharding (for scalable write operations).
Here are some resources for developers interested in learning more about getting started with MongoDB:
- The Windows QuickStart page on MongoDB.org
- 10gen's large and growing collection of MongoDB presentations
- Windows Azure Developer Center: Node.js Web Application with Storage on MongoDB
Microsoft's Channel9 says that the future videos in this series will cover the C#/.NET driver that 10gen has shipped for MongoDB, details of how to design and deploy replica sets, and various options for using MongoDB on Windows Azure.
