A goal-based configurable transaction model of artifact-centric workflows

Ensuring process execution reliability and success is crucial for business process management. A mechanism is required to link high-level requirements to transaction management and utilize runtime information to remedy occurred problems. However, workflow transaction models have a gap with high-level requirements, and their limited forward recovery mechanisms lead to lots of unnecessary aborts. This paper proposes a relaxed configurable transaction model derived from the artifact-centric design principle. High-level requirements are described using goal model and linked to transaction management. Algorithms are provided to ensure workflow validity against user-specified failure atomicity through validity rules. With the support of configuration rules and enhanced failure handling mechanism, some failures can be avoided when their restored conditions are satisfied by the runtime data gathered in artifacts.
