sql2nosql's Introduction

From SQL to NoSQL

Introduction

This is a demo project to show how to migrate from a legacy SQL project to a NoSQL project using Couchbase and Elasticsearch.

You will find the following git branches:

01-legacy/start the legacy project where we start from
02-restify/start we start to create a REST service (and remove old interfaces)
02-restify/end REST Service fully working
03-couchbase-persistence/start we start to move from Hibernate to Couchbase for persistence
03-couchbase-persistence/end Couchbase persistency fully working
04-new-ui-angular/start we start build an AngularJS GUI on top of our REST services
04-new-ui-angular/end AngularJS fully working
05-search/start we start connecting Couchbase and Elasticsearch and add search to AngularJS
05-search/end AngularJS with search fully working
06-dashboards/start we start to build Kibana dashboards
06-dashboards/end Dashboards fully working

To go a given step, just use git checkout command. Eg:

$ git checkout 02-restify/end

Look at the README file to have details on the current step.
