??? Applications of ETL workflows in data warehouses: Finally, the literature
reports several efforts (both research and industrial) for the management of
processes and workflows that operate on data warehouse systems. Jarke,
Quix, Blees, Lehmann, Michalk, and Stierl (1999) describe an industrial effort
where the cleaning mechanisms of the data warehouse are employed in
order to avoid the population of the sources with problematic data in the first
place. The described solution is based on a workflow which employs techniques
from the field of view maintenance. Schafer, Becker, and Jarke (2000)
describe an industrial effort at Deutche Bank, involving the import/export,
transformation and cleaning, and storage of data in a terabyte-size data warehouse.
The authors explain also the usage of metadata management techniques,
which involves a broad spectrum of applications, from the import of data to
the management of dimensional data and more importantly for the querying
of the data warehouse. Jarke et al. (2000) present a research effort (and its
application in an industrial application) for the integration and central management
of the processes that lie around an information system.
