Difference between Web service and RSS

[priya1221]

Hi All, I have a question regarding RSS...I am currently using web service to download data from server database to my mobile device(client) using web service which acts as a data access layer.Also through RSS we can download data... 1) Wat exactly is the difference between the two,Web service and RSS in terms of data fetch?? 2) In what scenarios can we opt for RSS(business use case)? Also when we create an xml doc on the server side how is it different from RSS i.e how can we say that it is an RSS feed? Kindly provide pointers to the above mentioned querries. Thanks in advance

Hi :) A web service is a vague description of a remote service capable of reading requests made, most likely, over http and replying according to a predefined set of rules. A "Service" in this case is an interface to underlying appliction/applications. The communication scheme, syntax and process rules, is also commonly called protocol. Such protocols include XML-RPC, SOAP and REST. RSS, Atom are examples of definitions for stuctured data such as news items etc In a web service call, such as an XML-RPC or SOAP call, you can include content such as RSS or Atom. A simple top down example of dependances in a web service call: RSS (Human Readable Data) | V SOAP (Method Call Defenition Protocol) | V HTTP (High Level Transport Protocol) | V TCP-IP (Low Level Transport Protocol) What you are aiming at, i guess, is the manner to make calls and handle responses, * REST (Representational State Transfer) services include most RSS and ATOM feeds. REST means that you use HTTP (GET,PUT,DELETE) as protocol for retrieving (GET), updating (PUT) and deleting (DELETE) items on the remote end. REST skips the overhead of SOAP/XML-RPC and is a very fast and light weight way of communicating with a web service. * SOAP (Simple Object Access Protocol) is however the most supported way of sending requests and recieveing responses on the CE platform. It is actually the technology of choice for the entire .NET paradigm. Its rather bulky though... * XML-RPC (XML Remote Procedure Call) is a very simplified protocol way of making Web Service calls. Because of its simplicity this is the choice for many developers outside the MS sphere. Hope this helps, Lars
