Design and Implementation of a Workflow Engine

Sebastian Bergmann » 25 September 2007 » in Articles » 4 Comments

After almost eight months of waiting, I am finally allowed to publish my thesis paper:
Design and Implementation of a Workflow Engine
This thesis discusses the design and implementation of a software component that faciliates the specification, management, and execution of so-called workflows. The discussion of this component's design includes the semantics and syntax of the underlying workflow model as well as the actual software design. The former builds upon the Workflow Patterns [BK03] terminology, the latter on the concepts of a Workflow Virtual Machine [SF04] and the idea that a workflow system should be comprised of loosely coupled components [DAM01, DG95, PM99].
The thesis paper is published under the Creative Commons Attribution 2.0 Germany license, the software that has been developed as part of this thesis has been released under the New BSD License as part of the eZ Components (Workflow).

You can find the thesis paper here.

    A workflow engine for PHP is nothing new. I designed and built one in 2004 based on Peri Nets. Take a look at http://www.tonymarston.net/php-mysql/workflow.html

    Tony,

    I knew about your work and referenced it as [TM04] in the thesis paper.

    Best regards,
    Sebastian
