Names of levels in Hierarchy

Just curious as to how people deal with names for the various levels of a hierarchy. I run into instances where I have to create the hierachies and have to come up with names for the various levels. I have been relunctant to use Level_1, Level_2, Level_3...etc because it doesn't seem very user friendly.

I've used Group, Category, Class in the names of the different levels. I'm interested in how others have handled this.

Jeff,
I just use the business terminology to name the columns.

You can use the “NamingTemplate” property, but without business input they most likely won’t like the names you choose. I would let them see the default Level_01, Level_02...and force them to decide on names.
