Getting start with JSON

XML and JSON are designed for standardized and simple way of describing different kinds of hierarchical data structures and to facilitate their consumption and transportation in a standardized way.

Advantage of JSON Over XML:-

• JSON is a valid subset of Python, JavaScript and YAML
• JSON parsing is faster than XML parsing.
• JSON is compact format.
• Formatted JSON is easier to read than formatted XML.
• JSON specifies how to represent complex datatypes.

Below is the example of JSON and XML format.

JSON

{
    "Customer": [
    {
       "id":"01",
       "firstName": "N",
       "lastName": "C"       
    }
 ]
} 

XML

<Customer >
   <id>01</id>
   <firstName >N</firstName>
   < lastName >C</lastName>
</Customer >

Clearly, if the data utilized by webservices grow, XML will loose an edge, Number of Bytes travelled between servers and clients is largely reduced if JSON is used for data exchange.
