As asked, done

Dear Sir/Ma’am.

  I was working on it, https://github.com/lschallenges/data-engineering 
and I am confused with item and price values as given in .tab file for data sample. Though i have altered them, as per my understanding.

I am also bit confused with the normalization process, as i am not sure about all classes, which you are using or created here. As i am unable to see, foreigh keys in given data sample. I am not sure, how precisely i would be able to maintain the normalization.

Thank you.
