DBA Job Functions

My boss is asking me to compile a list of typical job functions for a DBA. I came up with a brief list, but would like to hear any other recommendations that you might have. What he said was, “We don’t want to go into great detail, but not be too vague either. Somewhere between the 10,000ft and 1,000ft view.

Thanks in advance,
