Difference between OUI and DBUA? in oracle upgrade from 11g to 12c


Hi DBA experts,

Can someone please let me know what is the main difference between OUI (oracle universal installer)and DBUA-(Database upgrade assistant), why its needed to do DBUA after OUI activity.

I am preparing to start oracle upgrade on window system from 11g to 12 c.

your help is highly appretiated.
