An Introduction to Using CouchDB with Django
CouchDB is one of the more exciting projects—measured in number of semi-plausible day dreams it has inspired—I’ve run into in the past year. It is an ideological rival to relational databases, and instead of being focused on highly detailed schemas (long ints, varchars of length 25, and blobs of binary data, oh my) it deals in documents. These documents may be comprised of identical fields, but may also contain dissimilar fields, allowing the same flexibility as Google’s BigTable. Beyond that, CouchDB brings some other unexpected goodies to the table like document versioning.
