Towards a transactional services coordination model

Alberto Portilla, Christine Collet, Genoveva Vargas-Solar
2006 Proceedings - International Database Engineering and Applications Symposium  
However transactional properties have been poorly addressed using ad-hoc solutions at the back end of the systems.  ...  The objective of our research is proposing mechanisms for adding transactional behavior to services coordination.  ...  [18] proposes a workflow definition language to implement the saga model. [10] addresses atomic behavior to workflows by means of spheres.  ...

A discussion on approaches to handling exceptions in workflows

Fabio Casati
1999 ACM SIGGROUP Bulletin  
Finally, we introduce the exception handling techniques that we have developed within the WIDE workflow project.  ...  In this paper, we analyze the characteristics of the different types of exceptions that may affect the execution of a workflow, and present some approaches to their handling.  ...  WAMO [Eder95, Eder98] and Crew [Kamath98] extends this approach by providing more flexible and expressive models, more suitable for workflow applications.  ...

Workflow Exception Patterns [chapter]

Nick Russell, Wil van der Aalst, Arthur ter Hofstede

It is subsequently used to assess the level of exceptions support provided by eight commercial workflow systems and business process modelling and execution languages.  ...  This framework is independent of specific modelling approaches or technologies and as such provides an objective means of delineating the exception-handling capabilities of specific workflow systems.  ...  model) and a workflow (i.e. all of the process models in a given workflow environment).  ...

Concept of the exception handling system for manufacturing business processes

Misic Dragan, Domazet Dragan, Trajanovic Miroslav, Manic Miodrag, Zdravkovic Milan
2010 Computer Science and Information Systems  
Workflow management systems should be capable of responding adequately to the exceptions caused by the process environment.  ...  Business processes managed by information systems rarely operate according to the pre defined scenario. Exceptions to the pre defined workflows occur frequently.  ...  Acknowledgment The paper is part of project TR12010 -"Active product semantic data model" that is sponsored by Ministry of Science and Technology for the period of 2008-2010.  ...

Specification and implementation of exceptions in workflow management systems

Fabio Casati, Stefano Ceri, Stefano Paraboschi, Guiseppe Pozzi
1999 ACM Transactions on Database Systems  
We present Chimera-Exc, a language for the specification of exceptions for workflows based on detached active rules, and then describe the architecture of a system, called FAR, that implements Chimera-Exc  ...  Finally, we focus on the portability of FAR and on its unbundling to a generic architecture with detached active rules.  ...  Preliminary work on WAMO was extended in Eder and Liebhart [1998] , where the model was modified so that any activity can be the turning point from backward compensation to forward execution (based on  ...

Process and event modelling for conceptual design

Robert L. Nagel, Ryan Hutcheson, Daniel A. McAdams, Robert Stone
2009 Journal of engineering design  
Being based on functional modelling allows process modelling to integrate with functional modelling during conceptual design activities.  ...  With solely the generation of a functional model, the designer, however, runs the risk of failing to explicitly capture expected interactions and operations of the product as a whole.  ...  activity models (WAMO) (Eder and Liebhard 1995) provide modelling approaches for capturing project milestones, flow of project resources and basic scheduling information.  ...

Consulting past exceptions to facilitate workflow exception handling

San-Yih Hwang, Jian Tang
2004 Decision Support Systems  
In this paper, we propose an architecture model that deals with both expected and unexpected exceptions in the context of workflow management.  ...  The ways in which the previous exception cases were handled provides useful information in determining how to handle the current one.  ...  Acknowledgements This work is supported in part by the National Science Council in Taiwan under Grant no. NSC90-2213-E-110-022.  ...

Self-adapting recovery nets for policy-driven exception handling in business processes

Rachid Hamadi, Boualem Benatallah, Brahim Medjahed
2007 Distributed and parallel databases  
These recovery policies are generic directives that model exceptions at design time together with a set of primitive operations used at run time to handle the occurrence of exceptions.  ...  In this paper, we propose Self-Adapting Recovery Net (SARN), an extended Petri net model, for specifying exceptional behavior in business processes.  ...  Workflow change management Ellis et al. proposed a workflow evolution model which uses a meta-model to design workflows as special kinds of Petri nets [16] .  ...

Stefanie Rinderle Ma, Paul Grefen
2014 2014 IEEE International Conference on Web Services  
For this we analyze the combination of concepts from the worlds of transactional service compositions and process change.  ...  Based on the analysis results, we derive algorithms to deal with change in transactional service compositions. We discuss the algorithm design and their practical applicability.  ...  This standard defines abstract transaction models that inherit from the concepts in Fig. 2 : the Atomic Transaction model inherits from Strictly Atomic and Strictly Isolated, the Business Activity model  ...
