Basics of RESTful services:
REST stands for Representational State Transfer, it is a simple stateless architecture that runs over
HTTPwhere each unique URL is representation of some resource. There are four basic design principles which
should be followed when creating RESTful service:
* Use HTTP methods (verbs) explicitly and in consistent way to interact with resources (Uniform Interface), i.e.
to retrieve a resource use GET, to create a resource use POST, to update a resource use PUT/PATCH, and to
remove a resource use DELETE.
