  abstract= "Concurrency control mechanisms such as turn-taking,
     locking, serialization, transactional locking mechanism,
     and operational transformation try to provide data
     consistency when concurrent activities are permitted in a
     reactive system. Locks are typically used in transactional
     models for assurance of data consistency and integrity in a
     concurrent environment. In addition, recovery management is
     used to preserve atomicity and durability in transaction
     models. Unfortunately, conventional lock mechanisms severely
     (and intentionally) limit concurrency in a transactional
     environment. Such lock mechanisms also limit recovery
     capabilities. Finally, existing recovery mechanisms
     themselves afford a considerable overhead to concurrency.
     This paper describes a new transaction model that supports
     release of early results inside and outside of a
     transaction, decreasing the severe limitations of
     conventional lock mechanisms, yet still warranties
     consistency and recoverability of released resources
     (results). This is achieved through use of a more flexible
     locking mechanism and by using two types of consistency
     graph. This provides an integrated solution for transaction
     management, recovery management and concurrency control. We
     argue that these are necessary features for management of
     long-term transactions within \"digital
     ecosystems\" of small to medium enterprises."
