Example 2: soap vs rest

RESTful supports JSON, XML,
	SOAP supports only XML
REST is faster than SOAP based web services
	SOAP is more secure
REST allows a greater variety of data formats,
	SOAP only allows XML.
    
    1) SOAP
- Communication happens using XML only
- Request is sent to SOAP methods
- Documentation is in WSDL (Wizdal)
- Heavy, more secure, more stable
- getting less popular
    2) REST API
- Communication happens using Json, XML
- Requests are sent to API methods/urls using
- Communication happens in HTTP(Internet)
- Lightweight, stable
- Easy to develop and automate
- very popular
