Hi Venu,

In short:

Synthetic keys link tables that have more than one field in common. QV creates these keys automatically.

You need at least two tables in your data model.

Though you should carefully think about avoiding these keys, you might be able to live with them.

Circular loop means you have alternative paths between two tables, so you need at least three tables in your data model to run into this. QV can't live with circular loops, it will break the loop by loosely couple one of the tables automatically.

Thanks,

Thank you VERY MUCH!!

It's not only a very good introduction  to this theme, but also a warning to those who thinks it's only a matter of simply loading data but, more than that, it can take a big effort and is crucial for the correct deploy of business data information through the Dashboards.

Thank you again,

M.G.

This presentation is great! But there are images, or at least it says it should have, that are not showing up. I only see a reminder at the images place stating that "can't show image at this moment" or "Powerpoint prevents you from open this image".
