Abstract
The extract and transformation operation performed on multiple data sources. In the extract operation, a computing system periodically performs an extraction operation on the data sources, perhaps as defined by metadata. The transformation operation is performed on at least some the extracted data, and is periodically performed, perhaps also in a manner that is defined by metadata. When performing each iteration of the transformation operation, the computing system performs a transformation operation on valid data, marks other data as suspect (due to a dependency on data that is not present), and completes transformation on yet other data that had previously been marked as suspect or perhaps reaffirms its suspect status if the needed data is still not available.
