Hi Sir, It's a really good video. I have a suggestion: instead of loading data into Excel and then using it in Jupyter Notebook, we can directly connect to the database and use that view for our ML algorithms.
Hi, Thanks for a great suggestion. I did consider this earlier and used the pyodbc library to fetch data from server. However this method sometimes gives errors due to accessibility or drivers. So I didn't want the new learners to get discouraged by this, hence decided to keep it simple. Let me know if you have used any other library which makes the process simpler. Will be really happy to learn & use it in my next project. Thank you so much for watching! :)
@pivotalstats Sir, I have used 'from sqlalchemy import create_engine', but you are right; initially, during connection, it gives a really hard time due to drivers.
Please upload more project like this I want to do more like this(Power BI + SQL + Machine Learning) No other people are doing it. You're a GEM man! Love you
You've outdone yourself again. Thanks so much for giving this for free. Please do more projects like this using different data sources and different data analysis tools and techniques. Stay blessed!
It is a great end to end project, from getting a understanding about how data is converted from a raw data to visually appealing dashboard. Thanks alot.👍🏻
Just finished this project.I’m in awe of how well you took us through it!I’ve learnt so much and will definitely add it to my resume.I understood everything,you are incredible!! Keep up the good work👏🏽
Hi sir , thank you i just completed this project and i am adding it to my portfolio. You are a great teacher . Looking forward to more videos from you .
Hello sir, how are you? We don't talk or chat, but we've learned a lot from your videos. We're very grateful for teaching us, sir. Hope you're doing well and staying healthy
Hi, The main reason is to improve performance because in a reference table we can remove duplicates and reduce the row count. Also in future if I decide to add more mapping columns then its easier to manage in a separate table.
Isn't removing duplicates from single column (as we did in mapping) will affect the analysis outcome since their corresponding values in other columns are there in the data?
Hi, no that will not impact because we are working on a separate table. When the relationship is created between mapping and main table, it will assign relevant age group to each row.
Sir, thank you for the video. However, I don’t understand the creation of that production table at all. Similarly, what is the downside of removing null values at the time of importing the table instead of the rigorous activity later?
Glad you liked the video! 1. Creating a prod table is considered as a best practice because it gives you the opportunity to revert back to the original data in case you make any errors without running the entire data load process again. 2. We can always do the data cleaning part in power bi, but the problem with that approach is that in case you are working with a team, and all of them are working on the same data. Then each of you would have to do the same cleaning process on each of your files. Also lets assume that after sometime you add a new cleaning step to your file then that steps will have to be implemented on all files again. Hope this helps!
@pivotalstats Thank you so much for responding promptly. That's awesome. Pardon me if am being slow here, however, regarding the first question, how that production table was created was fast so I didn't get it even though I understand the reasons for the creation considering the fact that am more used to PowerBi than SQL. Regarding the 2nd part, I meant the initial time you were importing the file into SQL you didn't ignore the null values but you later tried to remove them during the query. Is there any special reason to it?
Hi, Since this project covers almost all major aspects of Data Analytics, you can write SQL Database Management, Power BI Data Transformation & Visualization, Data Analysis & Random Forest Modelling.
Hi, Thanks for the wonderful learning video. I'm able to follow and re-create all the charts, I'm just encountering one error in the Churn Reason sheet is showing "The Total Churn" against each of the rows (1732) and also the total is showing as (1732). Please guide.
Hi, Check the table from which you are dragging the Churn Reason column into the visual. Most probably you are using the Prod_Services table. Instead fetch it from Prod_Churn, that will solve the issue. Hope this helps!
Hi, thank you again for the great video. In my work, after creating the reference table ("Mapping age group"), in model view there is no connection between Via Age. Don't know why? I followed the exact path and rechecked. PS: I manually made a connection between them in model view, now I am getting correct results. This isn't incorrect, right?
@@pivotalstats thank you, still working on the project. Now half way is done. ☺️ Thank you once again, and highly appreciate your great contribution. 👏

Hi, Awesome Video...Really helpful. However, i am unable to understand where did the concept of VIEWS was handy while doing the churn analysis. Did i miss anything?
@pivotalstats that's why I missed it. I tried to practice only the churn analysis part. My bad. On a side note, I checked out a few videos of this channel, the content is pure gold. Kindly keep adding more.
Hi, it seems you might have made a spelling mistake somewhere in query. Can you copy the query from the link that i provided in description and try again.
I am getting the correct output but when I am going to my prediction data.xlsx file to see my result it is telling me Excel cannot open the file predictiondata.xlsx because the file or format is not valid
kia baat ha sir g, you are amazing. thanks for this all. I believe you are the only one on TH-cam who provides detailed lectures with full access to data and lecture notes. You did this very professionally. can't be better than this. Just waiting for more and more. Could you also please make a video on how to develop websites and how to upload all the projects onto it, as you did for yourself. thanks for this amazing work.
Thank you so much :) Reading such nice comments really motivates me to bring more quality content. I don't know if web development related content will be correct for this channel, but I will surely plan a video on creating your portfolio page on github. Cheers!
The error suggests that the Customer_Status column which is our Y variable (target variable), contains missing values. But in the original data there were no missing values in this column. Could you check if your vw_ChurnData contains null values? If it does then check the ETL process & Original Excel raw data file once more. Hope this helps!
You can use any of these ml algorithms but while I was researching on this topic, I found that random forest is the most preferred algorithm for churn analysis.
Hi , I can't connect to your server in Microsoft SQL Studio. Is it still possible to connect? I like this project and would to train on it also. why does this error appear?
Hi, you won't be able to connect to my server because that is my local server instance. You need to install sql server on your system and connect it locally. Hope this helps!

Hi, Check if you are entering the correct server name. I have noticed that many people entered the server name which is there on the video, but you should be entering your server name. Hope this helps!
Sir , provide data file not working on SQL server , error coming. When 1 error is solved, then another error is coming. It is better for us if you provide all 4 data files link.
Hi, May be I did not understand the question, but the data link I provided contains only 1 data file (not 4) i.e. Customer_Data. If you are facing errors even after following all the import process I showed in the video. May I suggest you to import that data directly to Power BI and do the transformations like null removal in the Power Query editor, so that you dont have to waste time on SQL server troubleshooting. Hope this helps!
