7. Apache CouchDB is a distributed, fault-tolerant and schema-
free document-oriented database accessible via a RESTful
HTTP/JSON API. Among other features, it provides robust,
incremental replication with bi-directional conflict detection
and resolution, and is queryable and indexable using a table-
oriented view engine with JavaScript acting as the default view
definition language.

17. “Django may be built for the Web, but CouchDB is built of the
Web. I’ve never seen software that so completely embraces the
philosophies behind HTTP. CouchDB makes Django look old-
school in the same way that Django makes ASP look outdated.”
— Jacob Kaplan-Moss, Django Developer
52. What CouchDB should
not be used for!
• A relational database.
• A replacement for relational databases.
• An object-oriented database. Or more
specifically, meant to function as a seamless
persistence layer for an OO programming
language.
