comment Learning Resources for Data Science in the Wolfram Language
In your chart I miss some nice examples on how to change values and append new columns and lines in current List/Associations/DataSet. Unfortunately L-value assignment are not working yet. What make such operations very difficult to Datasets, and make Datasets itself not very interesting to Data Science at the present stage. Another serious limitation is the memory issue, as you can see here.

Not clear what is the question. It's about public datasets? Maybe you can see kaggle.com

For Association form you can use this: Normal@GroupBy[ass, Key["SNO"], Values@*Query[All, {"PNO", "QTY"}]]/.Rule -> List?
