Workflow Modeling Using Proclets
Wil M. P. van der Aalst,Wil M. P. van der Aalst,Paulo Barthelmess,Clarence A. Ellis,Jacques Wainer,Jacques Wainer +5 more
TL;DR: This paper introduces and advocates the use of interacting proclets, i.e., light-weight workflow processes, by promoting interactions to first-class citizens to model complex workflows in a more natural manner, with improved expressive power and flexibility.
Proceedings ArticleDOI
The Chautauqua workflow system
TL;DR: The article discusses Chautauqua-its motivation, its design, and its implementation-the emphasis is on its novel features, and the techniques for implementing these features.
Proceedings ArticleDOI
Design and implementation of GORDION, an object base management system
Aral Ege,Clarence A. Ellis +1 more
TL;DR: An experimental object base management system called Gordion is presented, which provides permanence and sharing of objects for workstations within an object-oriented environment and its ability to communicate with multiple languages, introduction of new concurrency control primitives, and ability to manipulate objects of arbitrary size are presented.
