Transactional business processes; Transactional workflows
A transactional process is a partially ordered sequence of activities which is executed in a way that guarantees transactional consistency for all activities or a subset of them. Activities can be either transactional (e.g., they are again transactional processes or conventional database transactions) or non-transactional (e.g., invocations of application services). Activities are ordered by means of control flow and data flow dependencies.
In most cases, transactional consistency for processes focuses on notions of atomicity which go beyond the “all-or-nothing” semantics of ACID database transactions. This is done by supporting a process designer in explicitly specifying how consistency has to be achieved. Models for transactional processes include support for failure handling which can either be integrated into control flow dependencies (i.e., distinguishing between regular execution and...
