give an example of a transformation or aggregation you needed to make for your Group project. I understand that each group might have fewer transformations or aggregations than the group member number. In that case, you can also propose other transformations that would be appropriate (but you are not using for your project) or you can respond to another group's post in the form of a comment or question. I want to observe the critical thinking in tying a newly learned tool to an application you have been working on. You can use the Transformations and Aggregations mentioned in Ch 1 of the "Applying SQL to Real-World Problems" course for reference
