4. So, like, what does it do?
Classic NoSQL database
Brilliant replication out of the box
All data stored as JSON - There is no schema as such
All communication via your app to Couch is via JSON/
HTTP(S)
Can write map-reduce functions to sort/query/filter data
It’s faster then a traditional SQL DB (well, depends...)
Oh, and why we like developing with it.

developing modern apps easier
Using web-sockets from the browser to
NodeJS, and pushing live data changes from
Couch, makes developing fun!
