I know the syntax for using the Rank and Dense Rank functions
but I can’t find any uses in the real world for this .

For example DENSE_RANK

ranking       userid
1               500
1               500
2               502
2               502

and Rank

Ranking UserID
    1   500
    1   500
    1   500
    1   500
    1   500
    1   500
    1   500
    8   502
    8   502
    8   502
    8   502
    8   502
    8   502
    8   502
    15  504

I can’t understand how the 1,1 2,2 values would be useful in the real world.
On the other hand, I do understand very clearly what the real-world uses for row_number over partition are; I just can’t find what can I do with this kind of information (dense & regular rank)
