QualityStage 7.5 for DS7.5.2 or fuel for Data Stage 8.1?

We are purchasing QualityStage. Any recommendations as whether this is fuel for a DataStage 8.1 upgrade or if we should stick with DS 7.5.2. I don't have QS experience. I know that is part of the install with 8.1 and that is has been made more native. Does this mean it is part of the DS engine or does it have a seperate engine? Any GUI/client differences?

Thanks,
Ryan

starting version 8 quality stage application is integrated into datastage but need to have separate license for using quality stage jobs in datastage. it is gui and part of datastage engine, both QS, DS use same repository, the new features in ver 8.1 QS are improved match enhancement and standard quality assessment , where as in DS pivot stage is added in parallel jobs as it was only accessible in server jobs earlier

Substantial client differences, and substantial under the cover differences. Beginning in version 8.0, DataStage and QualityStage share the same Designer. There is no separate QualityStage engine; QualityStage stages become DataStage operators and these run in DataStage jobs (in line, rather than needing to exit through qsrtmngr). It's a tidier and cleaner interface.

Note, however, that this is only for parallel execution. If you run server jobs only, then you need to keep QualityStage version 7.5, even though you upgrade DataStage.

You get much better value for money with QualityStage 8.1 standalone than with version 7. When they merged it into DataStage the created a version that has a large subset of DataStage stages and functions in it so you get a big chunk of DataStage thrown in with you QualityStage purchase. If you purchase a DataStage license it unlocks some additional stages.

So in version 7 if you wanted to run QualityStage from a DataStage job (via the plugin) you need to license both products, in version 8 you can run QualityStage and many DataStage functions with just a QualityStage license.
