Data Quality - Data Quality Management-Data Quality Analyst-Data Quality Assessment-Data-Quality 

Dr. Farewell - Thank you for your nice comment! I tried to give examples of every data issue in this data quality video. You are welcome to connect with me on LinkedIn at www.linkedin.com/in/inderpsingh/ Regards, Inder P Singh - Blog: inderpsingh.blogspot.com/

Thank you very much 🙏 You may find my database testing tutorials useful, especially on data normalization and testing. They are at ru-vid.com/group/PLc3SzDYhhiGVVb76aFOH9AcIMNAW-JuXE

@Lijia Guo - Thank you for the sub.

Thiago Fragoso - Thank you for your positive comment! Though software QA can contribute to data quality, it's a specialized role focusing on data quality management and improvement. For example, the Data Quality Analyst may need extensive domain knowledge and provide high-quality data to Data Science teams, DevOps teams and of course QA.

Okay, I will look into it. Thanks for your concern.

Many thanks. If you want to learn Database Normalization, my tutorials are available at the link, ru-vid.com/group/PLc3SzDYhhiGXDgSwZxhNUmCYX7uAFN1Uu

Or maybe the FirstName AND Email value of the 2nd row are wrong or another issue. But, I designed this example of redundancy in my video (Jack and John are nicknames of each other). Thank you for sharing your thought.

@@QA1 Overall, the video is really informative. I already gave a thumbs up :)

@Athens Fitzcheung - That's an over smart comment! What are you trying to imply? I designed these examples and the slides. This content is copyright by me. You may not use it elsewhere. Thanks!

If you already have the data, you can explore it by plotting it. This way, you could see the potential data quality issues visually.

@@QA1 Can we do that by Excell or there is another software for that?

Excel is good. Or you could use Python libraries to plot the data.

Thanks!

@neetrab - You are welcome to the Software and Testing Training channel.

@murali chiyan - The simple answer is no, data redundancy is an issue of data quality. Good data should exactly one copy (non-redundant) for data integrity reason. However, sometimes data is duplicated (across partitions or disks or devices) for fault tolerance or performance reasons. That data redundancy by design is not an issue. Hope that I was able to clarify your query! Thank you!

Yes, I can.

@@QA1 please send me. to my user id.

How to send it to your user id!? Why do you need my ppt? Please email me.

@@QA1wahi mera email hai

Hello, my slides in this video are within a bigger ppt. I'll need to take time to search that ppt and extract the relevant slides to send.

ok
