Robert Hartmann

My name is Robert Hartmann. I am an M.Sc Computer Science graduate with a specialization in databases. I've worked as a DBA for 2 years now, and recently earned an MCSA certification in SQL Server 2012. My focus of interests regarding SQL Server lies in in-depth knowledge as well as query optimizing and tuning, though I also sometimes work with SSAS and SSIS. I try to be as simple as possible in my writing in order to reach as many interested readers as I can.
Outside of work, I have a beautiful son and am married enjoying my family. You can follow me on twitter, or simply subscribe to my RSS feed on http://dirtyread.de/.
