How does QualityStage work together with Datastage?

[olgc]

Hi there,

How does QualityStage work together with Datastage: as a plug in or write the result to some place, then Datastage read from it? Who will use the QualityStage: ETL developer or quality assurance staff?

It is said:

"WebSphere QualityStage analyzes data at the character level
and uncovers anomalies and buried data prior to transforming it for
database loading or transaction processing. Data from disparate
sources is standardized into fixed fields using business driven rules
to assign the correct semantic meaning to input data in order to
facilitate matching."

Thanks,

QualityStage currently can work independently of DataStage (processing files), or it can be invoked via a plug-in stage in which rows are passed to and fro along links as with any other DataStage stage.

In the next (Hawk) release QualityStage per se ceases to exist and there is a combined Designer for both DataStage and QualityStage - the latter has been extensively rewritten to use the common repository model.

The question about who uses QualityStage is difficult to answer; for example a data analyst might be interested in its Investigate capability, while an ETL developer would be more interested in the Standardization and Match capabilities. Someone developing a web service (in DataStage / QualityStage) to validate/certify name and address data might also be interested in the Survivorship capability. A marketing person might also be interested in Survivorship to determine households rather than best description of individual customers. And so on.
