LevelDB and Node: What is LevelDB Anyway?
This is the first article in a three-part series on LevelDB and how it can be used in Node.
This article will cover the LevelDB basics and internals to provide a foundation for the next two articles. The second and third articles will cover the core LevelDB Node libraries: LevelUP, LevelDOWN and the rest of the LevelDB ecosystem that's appearing in Node-land.

It has since seen very wide adoption across the industry and serves as the back-end to a number of new databases and is now the recommended storage back-end for Riak.
