Course Overview

CouchDB, is an open source database that focuses on ease of use and on being “a database that completely embraces the web”. It is a NoSQL database that uses JSON to store data, JavaScript as its query language using MapReduce, and HTTP for an API. One of its distinguishing features is multi-master replication. CouchDB was first released in 2005 and later became an Apache project in 2008.

This is a hands-on course on CouchDB. You will learn how to install and configure CouchDB and how to perform common operations with it.

Additionally, you will build an example application from scratch and then finish the course with more advanced topics like scaling, replication and load balancing.
