nested set design question

Hello group,

What are the benefit of using hierarchyid in nested set design in database? base on advice from one of the experts I am using nested set design and of course it has left and right integer values. Using hierarchyid will make a difference as far as optimization or adds up overhead ?

Thanks,
ak

The right and left will mainly be used for navigation. hierarchic is simply redundant information.

So does it mean using right and left is a better approach and has less redundancy in compare to using Hierarchyid data type?

if so, what do you suggest so I can prove this fact?

Thanks,

from what I using hierarchyid offers t-sql methods to manipulate data in a tree but on other hand it is a new type and I keep running into negative and positive comments on the web.

any comments?

I am using it  now, as newbie of course and it allows you to come up with simpler queries however, you are right ... it has some redundant information which replaces right and left params.

Thank you,
