Does Exchange Online pull from 0365 or does 0365 pull from Exchange?

I am not a microsoft expert, but exchange online is only used for standalone Exchange server and provided with Office 365. But Office 365 is for Cloud based Exchange service, so you only use Online if you have deployed your own Exchange servers (but wish to use the rest of 365 cloud suite).
So they are mutually exclusive, you would use one or the other and the data isn't synced in any way.
