20210512 Pikairos Simple question about Term Frequency

I have a table with a single column of text called Source. I have another table with a text column called Terms and a text column called Category.

I want to create a table that shows each Term, its Category, and the number of times that Term exists in the Source table.

There seem to be a lot of ways to approach this. Any ideas of best practice?
