Deferred Tax Asset vs. Deferred Tax liability

I am confused on the difference acounts that affect DTA and DTL. Specifically, how would we know if an account changed DTA vs. changing DTL (either increasing or decreasing)?

I wrote an article on DTAs and DTLs that I think covers this: http://www.financialexamhelp123.com/dtas-and-dtls-how-to-keep-them-straight/

Full disclosure: as of 4/25 I’ve installed the subscription software on my website, so there’s a charge for viewing the articles.
