TL;DR: An AI-based architecture that automatically manages workflows is developed and a prototype that executes on top of a distributed computing environment is implemented to help a telecommunications company better provide a service that requires coordination among many operation support systems and network elements.
Abstract: We have developed an AI-based architecture that automatically manages workflows, and we have implemented a prototype that executes on top of a distributed computing environment to help a telecommunications company better provide a service that requires coordination among many operation support systems and network elements. The activities involve several database systems, user interfaces, and application programs. >

TL;DR: An architecture based on AI technology that automatically manages workflows is developed that executes on top of a distributed computing environment and has been applied to automating service provisioning workflows.
Abstract: Workflows are the structured activities that take place in information systems in typical business environments. These activities frequently involve several database systems, user interfaces, and application programs. Traditional database systems do not support workflows to any reasonable extent. Usually, human beings must intervene to ensure their proper execution. We have developed an architecture based on AI technology that automatically manages workflows. This architecture executes on top of a distributed computing environment. It has been applied to automating service provisioning workflows; an implementation that operates on one such workflow has been developed. This work advances the Camel Project's goal of developing technologies for integrating heterogeneous database systems. It is notable in its marriage of AI approaches with standard distributed database techniques. >

TL;DR: This work has developed a general specification facility that enables the formalization of any transaction model that can be stated in terms of dependencies amongst significant events in different subtransactions, including start, commit, and abort.
Abstract: Extended transaction models have drawn much interest recently in academia and industry [2]. Such models seek to address the limitations of traditional ACID transactions for supporting multisystem applications that operate in heterogeneous environments. Such applications are increasingly proving to be of strategic importance to a number of businesses and governmental agencies. Different transaction models, however, tend to be closed in that they cannot be easily combined with other such models, thus limiting their applicability to situations which exactly match one of them. We do not propose yet another transaction model. Instead, we have developed a general specification facility that enables the formalization of any transaction model that can be stated in terms of dependencies amongst significant events in different subtransactions. Such significant events include start, commit, and abort. We make no assumptions that these are the only kinds of events. Our approach is viable because most extended transaction models can be naturally formalized in terms of dependencies among different subtransactions.
