Point Tick Value and Tick Size

 
Dear MT4 Users,

I am a bit confused about these three variables.
Taking DAX for example (#FDXU1):

Point: 0.1
Tick Size: 0.5
Tick Value: 12.5


While I understand that tick size is the minimal movement up or down on the prize, and tick value is the real monetary value of a tick,
I fail to understand what significance Point bears.
Also looking at the stock market I get info about tick value and tick size for every product, however Point only appears in MetaTrader.

Can someone please explain the meaning behind Point?

Thank you!
