Apache CouchDB

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.

CouchDB Document

A CouchDB document is simply a JSON object.

This is an example document:

{
 "_id":"some_doc_id",
 "_rev":"D1C946B7",
 "Subject":"I like Plankton",
 "Author":"Rusty",
 "PostedDate":"2006-08-15T17:30:12-04:00",
 "Tags":["plankton", "baseball", "decisions"],
 "Body":"I decided today that I don't like baseball. I like plankton."
}
