MongoDb Data Modeling Notes - v1.0

This is a rough document getting prepared for db design and architect level decisions to be made while dealing with area where one wants to consider MongoDB abd web services.

The tools would mainly include mongoDb, RSTful resources, background jobs, and possible queuing engine(RabbitMQ) to provide unit inputs to the background jobs. After measurements caching layers like ElasticSearch can be introduced as require. MySQL can be considered in few cases to support non-relational data storage as per need.

RESTful services and background jobs can be implemented using best frameworks available in Java. Or now a days extreme-service-developers are talking about wonders of Go language, hence would be great if Go language is considered for writing service layer. This is one very nice article about the REST services in Go
