HI,

I am doing PHD first year in web services and cloud computing, I need some details about Web Services.
That is, What are all the styles are available to implement Web Service?

As of now I heard that that following styles are available
1. Synchronous ,
2. Asynchronous (Comet,Pull,Callback)

Is there anything more.
This is first time I post here, If I did any mistakes , please forgive me.

Thanks in advance
