Providing transactional behavior to services coordination
Alberto Portilla · 2006
Our research project proposes an approach for providing transactional behavior to services coordination. In service composition functional aspects have been successfully addressed. However transactional properties have been poorly addressed using ad-hoc solutions at the back end of the systems. This situation makes current applications not reliable and not adaptable to existing distributed environments (i.e. Internet). The objective of our research is proposing mechanisms for adding transactional behavior to services coordination. 1 Context and motivation Service composition is an accepted paradigm for building information systems. This kind of systems are not built from scratch, but using existing software components called services. A service is an autonomous software that offers some functionality through a network [1, 2, 7, 25]. Furthermore, services coordination can be used to abstract an application logic by capturing the interactions and dependencies among services. Functional requirements describe the application logic. Several approaches have been proposed to tackle the problem of describing and enacting the services coordination [21, 6, 3].
