drei wesentliche Anforderungen an die Transaktionsunterst{\"u}tzung f{\"u}r Workflows:
Zun{\"a}chst mu{\ss} das WFMS selbst Manipulationen seiner eigenen Ressourcen unter
Transaktionsschutz durchf{\"u}hren. Weiterhin ist die M{\"o}glichkeit des gesicherten
Aufrufs von Transaktionen und deren Gruppierung zu verteilten Transaktionen zu
erm{\"o}glichen. Schlie{\ss}lich ist die Unterst{\"u}tzung von langen Transaktionen zu
gew{\"a}hrleisten, die sich aus der Semantik der abgebildeten Gesch{\"a}ftsprozesse
ergeben.
Based on the exploitation of workflow management systems in practice three
essential requirements for transaction support for workflows result: First, the
WFMS must perform manipulations of its own resources under transaction
protection. Next, the ability of protected invocations of transactions as well
as their grouping into distributed transactions must be provided. Finally,
support of long running transactions resulting from the semantics of the
represented business processes has to be ensured.}, url = {http://www2.informatik.uni-stuttgart.de/cgi-bin/NCSTRL/NCSTRL_view.pl?id=ART-1997-13&engl=0} }

effective and productive. Consequently, existing applications must be modified,
and new applications must be written. The new applications typically run in a
distributed and heterogeneous environment, performing single tasks in parallel,
and demanding special transaction functionality for the supporting
environments. Workflow-based applications offer this type of capability. In
this paper, their principal advantages are derived and set in context to
transaction, object, and CASE (computer-assisted software engineering)
technology. In particular, a method is proposed to develop these workflow-based
applications in a cohesive and consistent way.}, url = {http://www2.informatik.uni-stuttgart.de/cgi-bin/NCSTRL/NCSTRL_view.pl?id=ART-1997-12&engl=0} }
