C. Mohan in his 4th post about the NoSQL space : So, here is my humble request to the NoSQL techies: For each of your systems, please send me or point me to detailed technical information on each of the important aspects of your system. This should be documentation in the form of papers or presentations, and not pointers to source code comments and such!
Getting Started with NoSQL « myNoSQL
Couple of weeks ago, I had the pleasure to sit down with Mathias Meyer, Chief Visionary at Scalarium, a Berlin startup and discuss NoSQL adoption. Like myself, Mathias is really excited about NoSQL and he uses every opportunity to introduce more people to the NoSQL space. Recently he gave quite a few presentations around the Europe about NoSQL databases. The discussion has focused on how would someone start learning and using NoSQL databases and the path to follow in this new ecosystem. Below is a transcript of our conversation.
The relatively young but rapidly growing " nosql " community met last Thursday in San Francisco. The idea was to give attendees a solid introduction to how distributed, non relational databases work as well as an overview of the various projects out there. If I may say so myself we succeeded in doing both. Thanks to all the presenters for very interesting talks and everyone for great hallway discussions.

CouchDB
CouchDB provides a RESTful JSON API than can be accessed from any environment that allows HTTP requests. There are myriad third-party client libraries that make this even easier from your programming language of choice. CouchDB’s built in Web administration console speaks directly to the database using HTTP requests issued from your browser. CouchDB is written in Erlang , a robust functional programming language ideal for building concurrent distributed systems. Erlang allows for a flexible design that is easily scalable and readily extensible.
