Binaergewitter NoSQL

I recently was part of the first episode of the (German language) podcast "Binaergewitter" (roughly: Binary thunderstorm).
The first episode had "NoSQL" as a topic and the four of us talked for 2 1/2 hours about everything in the NoSQL space. We hopefully gave a pretty decent overview over the subject. People seem to like it so far :)
If you always wanted to know what column stores, datastructure stores, document stores, key value stores and graph databases are and German is your cup of tea, you should give it a go.
