CouchDB

I've been trying to figure out how to make MySQL or SQLite play nice with DCI, and there always seems to be some compromise when I design the interaction. In response to this, the default data storage method for Wax (besides SQLite) will be Apache's CouchDB.

CouchDB is a project started out of the need for a document-based database rather than a relational database. The bulk of web applications don't ever use most of the power of a relational database like MySQL or PostgreSQL, so why not use a data-storage solution that is more scalable outside of the application itself?

CouchDB uses HTTP to store/fetch data, using the 4 major HTTP request types: GET PUT POST and DELETE. The entire database is directly queried through HTTP, meaning that data can be requested directly from PHP or JavaScript, allowing for a more fluid interaction between the client and the data itself, and less need for requests back to the webserver.


CouchDB binaries are available for Mac OS X and Windows XP/Vista, and most package management systems for Linux have a CouchDB package.
