include file vs db queries

Well, imagine that my menu is the following:
home / about / products / contact

If i clicked "contact" from the menu, the contact-page
appears inside the i-frame. But i want to display a title
there "Contact" so people know where they are.

But if i change "contact" in the menu, i want the "contact"
on the contact-page to chgange as well.

This isn't the actual case, but it's quite similar..

Thanks in advance!
