Question for all who are interested in learning IAM

IAM is basically a roadmap for heap's data pages. Then why do we call this Index Allocation Map.

In sql2005 onwards this has started allocating INCLUDE columns for non clustered index, BLOB and row over flow data etc as well.

Is there a question here?

Not just heaps.

In sql2005 onwards this has started allocating INCLUDE columns for non clustered index, BLOB and row over flow data etc as well.


Include columns aren't reflected in, nor do they affect IAM pages.
