What is the difference between Obama's debt and Trump's deficit? Stent they, essentially the same thing?

I don't mean to start a shit-storm and please feel free to refer to and comment on Reagan, Bush 1,Clinton, Bush 2's policies as well. I am sincerely curious to learn the difference. 

Thank you and I apologize in advance if I've stirred and negativity.

The large fiscal deficits of the early Obama years can be justified economically as a fiscal policy response to the 2008-09 recession. In many economic theories, the deficit ought to be countercyclical: larger deficits in recession, smaller deficits during economic booms. 

No similar justification exists for the current level of deficit spending.
