First of all, thank you very much for the project. But there’re couple of concerns which you may have overlooked - 1. In every query where we’re doing analysis based on sales, I guess it’s better to consider sale_price*quantity as sales rather than sale_price only 2. In the last problem, profit should have been taken into consideration rather than sale_price But again I’m repeating that, above are some modification we can make to get the best business answers, otherwise in the video you’ve shown the approach how to handle an end to end project - from that pov it’s absolutely fine. We students can make necessary changes.
You sir, are a wonderful teacher! I am currently learning Data Engineering. This video has enabled me to catch up and understand some core concenpts that I found challenging because I missed live classes. Thank you!
I thoroughly enjoyed this video and followed along with you. Thanks for this. Please keep posting more of such end to end analysis problems. Thanks a ton for taking the effort to make these videos so that we keep learning :)
Today only i was seraching for data analytics ..and just saw your vedio ...thank you so much..pls post more such content on data analytics and any course on this as well please 😊
Great start for learning. Provided complete knowledge how the ETL works and improved the self confidence. Thank you so much for wonderful lecture about the project
Bro I think you have done mistake in top 10 highest revenue generating products category you should use SUM(orders_quantity*selling_price) because sum of only selling price cannot produce the revenue it should be multipied by quantity
Hello Ankit Sir, am a fresher and am looking forward to start my career in data analytics or data engineering field. This video is awesome and very helpful for me. Thank you so much for making the End ot End videos like this. And the way you explaining each and everything is very nice and clear. Keep it up Sir
Can't add the ODBC Sql Server even after having the MySQL that was installed for working on your SQL Course. I am getting an error message saying TEST FAILED. Can you please share any link that can help us to get that server name present in the list of servers available to connect or better a follow up video showing how to do it on your system. Thanks in advance
Hi, please review the code at 28:05, I'm a bit confused when you have done group by product_id. I can see multiple entries of the same product "sub_category " with different product_id; hence grouping by product_id will not reflect the actual revenue generation for each product. So, I have done the following: SELECT sub_category AS product, sum(sale_price) AS sales FROM df_orders GROUP BY sub_category ORDER BY sales DESC LIMIT 10;
Very nice video. Just a little doubt. In the last question we have to calculate subcategory with highest growth by profit but in the video highest growth by sales is calculated. So the one given in the video is right or not?
Hi Ankit, Thanks for your video. I work at a company where we load 70-80 files into our database each month. These files can be in formats like CSV, XLSX, or TXT etc..., and they all contain data. While each file is similar, there are always some differences. Currently, we use bulk insert in SQL Server to handle this, but things can go wrong, leading to some manual work. For example, one of the files might look different from the previous month. Do you think it would be better to use a mix of Python and SQL Server for this task, or is SQL Server sufficient? I feel that SQL Server's error messages can be poor, making it hard to troubleshoot why a table sometimes fails to load. Thanks!
"for each category which month had highest sales" above question has different output from your youtube video and sql queries that u have provided in sql file.
In the last question of sql Should we calculate growth by profit change or sale change because the question is for profit change Also in total revenue quantity of each order is not included

I assumed the sale_price is the result of this calculation, which would make the way he does it correct.

Thankyou so much Ankit sir For this project👍
Well done! The sales price column should be multiplied by the quantity since there is a discount on each product
You are right, I should have mentioned that!
I liked the way you explained every query... Keep it up..
Thank you so much 🙂
how do you document your findings. please make a video on how you put everything together for a portfolio showcasing your skills in python and sql

Thank you ankit it's really helpfull.
Can you make a practical video on A/B Testing plzz
Sure
cant't we direclty open csv file in python using read_csv no need of kaggle API
