I also have read that Diners Club International is a business unit of Discover Financial Services.

But MasterCard and Discover are 2 different financial companies that actually compete with each other.

So what's the relationship here?

How may it affect how I use the cards, since I also have a regular MasterCard and Discover card? Of course my goal is to maximize my miles and points.
If you have a US card, then you have no connection to Discover, full stop -- you have a Mastercard.
