Apache: Big Data 2015

Apache CouchDB does two things other databases don't: it replicates and it speaks HTTP as it's primary protocol. These unique qualities all you to build applications that are "of the Web" but that can also move "off the Web"--into your local network, your farm equipment, or the phone you're carrying.

In this tutorial we'll take a look at CouchApps. CouchApps are application logic (index definitions, document and result templates, validation functions) that live inside a CouchDB database along with the static HTML, JS, CSS, and images needed for the UI.

In this tutorial we'll take a look at various tools for building, integrating, and deploying CouchApps. We'll take a deep dive into building a CouchApp: both the thought process and the code. Near the end, we'll throw a replication party--moving the app between attendee devices sharing the app and it's accumulated data.
