Sometimes non-accounting people get hung-up on the words "debit" and "credit" and think they have to do with "owing" or "being owed" money, being "positive" or "negative", etc.
The effect of a debit or credit on the business depends on the accounts in the transaction and debit and credit don't have anything to do with the "direction" of a flow of money.
My 100-level accounting instructor summarized it as: "A debit is the entry in the left column, and a credit is an entry in the right column." Without the context of the specific accounts being debited or credited the terms themselves don't confer significant meaning.
A basic knowledge of bookkeeping and accounting terminology can confer near "super powers" when it comes to dealing with finance people. It's easy to learn and worth the time.
Double-entry bookkeeping is one of the oldest and longest-practiced "IT" disciplines. Your work probably touches revenue / expenses for your employer and someday you'll need to interface with accounting or finance people. Being able to speak the language, even poorly, has helped me gain trust and credibility that I don't believe speaking only in IT terms would have.
