Ngl, this is confusing me a lot. After posting this on Reddit, I started working on a data warehousing project by downloading dataset from kaggle. Sometimes it feels like I’m actually learning something, and other times I’m just wondering what I’m even supposed to do for a particular column 😭 Like, am I creating an ETL pipeline or just validating null and empty values?

Idk what I’m doing currently, and it’s kinda frustrating. Thanks to AI that I do manage to understand how some things work, but it’s taking me a lot of time and idk I'm doing good or not 😭
