This document summarizes CouchDB, a document database that uses JSON documents with dynamic schemas, is written in Erlang, and uses MapReduce functions for querying and aggregating data. It discusses CouchDB's features like multi-version concurrency control, incremental replication, and storing data and queries separately through views. The document provides examples of basic CRUD operations, views with different parameters, and modeling data in CouchDB using CouchRest::Model. It notes both benefits like a RESTful interface and caching, as well as downsides like performance and lack of tools.
