I am a Systems Analyst by profession.
There is a lot that I dont know, and a lot I wish (& try) to learn.
When it comes to software, I am interested in modeling,
languages (for modeling and development),
databases (a database is an application),
testing (the best way to learn the truth),
systems administration (it's not enough to make a system it's more important to keep it running),
editing (modifying data is a topic that deserves more attention)
