1.  Backups!
2.  Tuning & Optimization (indexes/procedures/etc)
3.  DB day-to-day Administration
4.  writing SQL code for day-to-day problems/checks/etc
5.  writing SQL code for projects/data migration/etc

Not necessarily in that order, but backups is definately #1!  I may have
missed one or two but these should be it for the most part.
