When to prefer JSON over XML?

Question

My requirement is just to display a set of values retrieved from database on a spread. I am using jquery.

Answer 1

Using JSON

• If the data is to be consumed by JavaScript in the browser.
• Data model is simple and not complex(too many composite objects).

Using XML

• Mostly in an SOA kind of environment where you are integrating several services on heterogeneous platforms and technologies.
• SOAP has an advantage that it can be transmitted across different protocols other then HTTP.
• Easy to use in data model transformation tool like XSLT,XSL-FO etc.
• Lot of Database support to store/query(XQuery) XML data.
• XML is a very mature data format so you would find plenty of tools to support any use case that you can think of.
