+<h3>Description</h3>
+
+<p>Window function: returns the rank of rows within a window partition, without any gaps.
+The difference between rank and dense_rank is that dense_rank leaves no gaps in ranking
+sequence when there are ties. That is, if you were ranking a competition using dense_rank
+and had three people tie for second place, you would say that all three were in second
+place and that the next person came in third. Rank would give me sequential numbers, making
+the person that came in third place (after the ties) would register as coming in fifth.
