"Model-driven Development of Web Service Transactions";
Report No. TUV-1841-2004-27, 2004; 16 pages.

Composite Web service design using model-driven approaches has been
in use for several years now, but the modeling of transactional properties
is still uncommon and has not yet been subject to much research. For
a distributed system of autonomous components like Web services, especially
when they are used for implementing business processes, transactional
guarantees can be of vital importance. In this paper, we propose a
model-driven approach which introduces a separate design layer dedicated
to transactions. We show that our systematic modeling approach is able to
introduce transactions in the design without increasing the complexity of
the basic UML diagram. Our approach can also be reused to specify other
properties of Web services such as security requirements or workflows in
additional layers.
