>but you may pretty much view REST as the SQL of the Web, and RPC as stored procedures.

Indeed, but that just raises the question: what would possess you to write an app out of SQL calls rather than general functions? So then why do the Web equivalent thereof?

[BerislavLopac]

You don't, of course. What you do is build an app which is using REST to store data somewhere online, and the app itself may be in the user's browser, on a mobile phone or anywhere else for that matter.

[SilasX]

Definitely. Just pass that memo along to the "apps should work purely through REST API calls" crowd.
