Abstract
This paper describes the design of a model as well as an architecture to provide support for distributed advanced workflow transactions. We discuss the application of transaction concepts to activities that involve integrated execution of multiple tasks over different processes. This kind of applications are described as transactional workflows. The classical commit protocol, used in many commercial systems, is not suitable for use in multilevel secure distributed workflow database systems that use a locking protocol for concurrency control. We choose to develop formal framework for secure distributed workflow architecture since we are actively involved in building a prototype of such a system. We strive to develop a practical logical characterization of multilevel secure (MLS) distributed workflow for the first time using the inherently difficult concept of non-monotonic reasoning.
