REST is just a software architecture style for exposing resources.

Use HTTP methods explicitly.
Be stateless.
Expose directory structure-like URIs.
Transfer XML, JavaScript Object Notation (JSON), or both.

A typical REST call to return information about customer 34456 could look like:

http://example.com/customer/34456

Have a look at the IBM tutorial for REST web services

REST is somewhat of a revival of old-school HTTP  where the actual HTTP verbs  commands  have semantic meaning   Til recently  apps that wanted to update stuff on the server would supply a form containing an  action  variable and a bunch of data   The HTTP command would almost always be GET or POST  and would be almost irrelevant    Though there s almost always been a proscription against using GET for operations that have side effects  in reality a lot of apps don t care about the command used    With REST  you might instead PUT  profiles cHao and send an XML or JSON representation of the profile info    Or rather  I would -- you would have to update your own profile       That d involve logging in  usually through HTTP s built-in authentication mechanisms    In the latter case  what you want to do is specified by the URL  and the request body is just the guts of the resource involved   http   en wikipedia org wiki Representational State Transfer has some details
