CouchDB is a document-oriented database that uses JSON documents, has a RESTful HTTP API, and is queried using map/reduce views. Each of these properties alone, especially MapReduce views, may seem foreign to developers more familiar with relational databases. This tutorial will teach web developers the concepts they need to get started using CouchDB in their projects. CouchDB’s RESTful HTTP API makes it suitable for interfacing with any programming language. CouchDB libraries are available for many programming languages and we will take a look at some of the more popular ones.
