[@shubhanshusahuu]

Good tutorial I got the point

[@imsujitpaul]

Thank for the video. I have two questions, is it possible to design a fact table with multi level grain? And if it is possible to design a fact table without any grain?

[@sandeeppai25]

No. There should be grain defined before creating any fact. If not defined properly, it will result in inconsistencies

[@jayanthibhavani1764]

Good content all I want to say is please speak little slow so that your sentences are much clear. I had to go back and forth in the video multiple times to understand the whole statement.

If you change to .75 speed, it is a little easier to keep up with.
