Dear All,

I found in my database my tables sizes is coming around 30TB (All Tables in Database). and my index size for the same is 60TB. This is data ware housing environment.

How the index size and table size are differing?

Why they are differing? why index size is bigger than table size?

How to manage the size?

Please give me clear explanation and required information on the above.

Regards
Suresh
