Just humble suggestion: instead of using slides full of texts, i think it will be better if you can explain using a real-life scenario or relatable animation or pictures or examples. That will be a lot more helpful for people to follow and understand these difficult concepts. Thanks.

I stumbled on this video while searching for "Why is data modeling important?" & here I am seeing the same reading material from guru99 website used on slides. Not being mean because I respect all content creators but how this video is different than going on guru99 website and reading the same thing from there. I think most people come on YouTube to understand stuff in simple terms and a well-explained manner. To be honest, this video did not clear any doubts I had because the text sounds same as bookish language(that guru99 used on their website), you could have used examples to explain, interesting visuals, diagrams to show the process of modeling etc.

your video looks like you are only reding the slides.

You are just clearly reading slides, It was a waste of time, please improvise.

Don't just read copy pasted definitions. I could have done that too. Explain in the most plain language?
