A Generic Data Warehouse Architecture f...

This paper proposes an approach to represent and analyze the content of workflow logs in a data warehouse. When analyzing workflow logs one big problem arises: typically, an underlying workflow model consists of loops (frequently interleaving), often implemented by using goto-statements. These structures increase the number of possible execution paths significantly - in theory even indefinitely. In a naive Data Warehouse (DWH) implementation one would represent all possible execution paths by means of a dimension. However, this would lead to a huge or even infinite number of elements in the dimension. In this paper, we present a novel approach for analyzing workflow logs including loops and goto-statements.
