In recent years, numerous transaction models have been proposed to address
the problems posed by advanced database applications, but only a few of
these models are being used in commercial products.
In this paper, we make the case that such models may be too
centered around databases to be useful in real environments. Advanced
applications raise a variety of issues that are not addressed at all
by transaction models. These same issues, however, are the
basis for existing workflow systems, which are having considerable
success as commercial products in spite of not having a solid theoretical
foundation. We explore some of these issues and show that, in many aspects,
workflow models are a superset of transaction models and have the added
advantage of incorporating a variety of ideas that to this date have remained
outside the scope of traditional transaction processing.
