What is the significance of pH in a basic solution?

Thank you for your replies everyone. I do know that water dissociates, but I still don't understand the significance of pOH in an acidic solution and the significance of pH in basic solution.

Acid produces hydrogen ions in water, but the hydroxide ions come from the water and not from the acid? What is the point in counting the water's hydroxide ions toward the calculation of pOH for the acid? I'm not sure I get it... all I know is that water dissociates into both hydrogen and hydroxide ions. But acid dissociates ONLY into hydrogen right? So where does the pOH for the acid come from? And pH for the base? Am I missing something?
