Date Hierarchy. Sometimes when I create a visualization in Power BI desktop with date and sales data, it automatical sets it up with the date hierarchy. I had one visualization set up this way and then added a new data base that had dates in it. I used the date to manage the relationships.
There's recent evidence that Bat's might be related to primates. bats, believe it or not, are mammals that have the same background as us humans. we share a distinct appendage pattern with 5 phalanges. as humans, the bats are related to whales, primates, mice, cats, dogs, etc.... if ur looking for a close relation, u wont find one, because the bat is a very unique evolutionary development.
But now we know that there is no such thing as a featherless bird. We know that bats are MAMMALS, just like people. Some of the things that tell us bats are mammals: 1  bats are warm blooded. 2  bats nurse their babies with milk.  bats have fur.
