Advanced transaction models in workflow contexts

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