              Q. Can we perform transactions using Web Services? If yes, how?
A: Yes. We can perform transactions in Web Services. This can be done by using 
the WS-Coordination specifications, which provides a framework for defining 
co-ordination types.

There can be many participants in a Web Service, thus forming large distribute 
apps. The WS-Coordination specification defines 2 co-ordination types:

WS-AtomicTransaction (AT)
WS-BusinessActivity (BA)

AT is used to co-ordinate short duration activities executed withing limited 
trust domains.

BA is used to co-ordinate long duration activities.

A Web Service app can include both AT and BA.

Cheers,

Ajay Singala [Synergetics].
