Research Issues in Large Workflow Management Systems (1996)
Gustavo Alonso, Hans-jorg Schek
In this position paper we describe what we believe are fundamental weaknesses of existing commercial workflow products and how database technology can be used to address these issues. By exporting...
Database Technology in Workflow Environments (1996)
Gustavo Alonso, Hans-Jörg Schek
Introduction If there is any proper characterization of the information resources of any modern corporation it will be as a collection of widely heterogeneous, largely distributed and loosely coupled...
Providing High Availability in Very Large Workflow Management Systems (1996)
