Process aware Data Quality assessment


Data quality (DQ) has been recognized as an important issue for optimal business decisions [TDWI]. Considerable work has been done on improving defected data. However, less attention has been paid to preventing data to become defective at the first place.

On the other hand, business process management becomes more and more relevant in every day business. Currently, there are many standardized business process languages available (e.g., BPMN specification).

Our research addresses the issue of data quality given that data and resources are managed by business processes. In particular, the idea is to find causes of low data quality in the processes that generates the data. Based on the causes, the next goal is to find ways to improve data quality by changing those processes and preventing the data from becoming defective.
