Uniform Access to Data in Workflows

Uniform Access to Data in Workflows

Abstract

Data aspects in workflow systems did not yet receive the same attention as process aspects. Various kinds of data are processed in workflow system: from case data to process data, from internal data to access to external databases or document exchanges in inter-organizational workflows. We propose a uniform treatment of all kinds of data in workflow definition and provide abstraction mechanism which allow transparent access to all kinds of data in a uniform way. We use XML as data access language in our workflow definition language WDL-X. The concept contributes to transparency of data location and logical and physical data independence of workflow systems. It facilitates the reuse of predefined activities and subworkflows on different data sets and eases the interaction of a workflow with its environment by abstracting from the actual representation of data.
