That isn't easy, but ok, here you go!

- to pivot:
To exchange the dimensions of the cube. It is like rotating.

- drill through:
In an UML diagram it would be, that you could double click on a use case
used in an use case diagram and another use case diagram is opened, which
describes the clicked use case more in detail.

- dice:
Image a big cube as your modell. Now you dice into it and look at a small
cube part of the big one. The dimensions remain the same, you just changed
the value range.

- slice:
Take a knive and cut the cube in slices. By doing this you focus on a
category.

- drill down and roll-up
Getting more details and the other way around, getting an overview.

These are the basic technics to navigate through an UML modell. It is just a
thing to think about. It doesn't say anything about it how to handle it.
These are just operations you can do with every modell.
