Yes, it is based on the naive set theory, but it was invented with having banking transactions in mind.

I am no accountant, but the accountants that I have come in contact with have told me that they love the tabular form in databases.

Strictly speaking, what is the definition of "relational"? It's based on the naive set theory. It allows you to select a subset and do nasty stuff with it. It allows you to do joins and Cartesian products. It allows operations like minus, intersect and union. Strictly speaking, I wouldn't call UTL_MAIL or DBMS_XDB relational, but who cares?

Fails and Kardashians are interesting, I do agree with that.

I am a techie. I am not sure that I would be capable of managing a company or that I would even want to. I don't know how to do it right. I can only give advice about a very narrow spectrum of the IT technology. Quite frankly, that worries me. If Oracle goes the way of the dodo, my entire career will go down the drain. Fortunately, Larry looks fit and buff and will hopefully live forever.
