I must thank you for the efforts of bringing this subject in the stairway series because as a T-SQL developer I was always a little confused by terms like "subscription", "publisher", and some others. Your articles explain with detail and are easy to read even to beginners in database administration like myself.
I said it before and I'm going to say it again. A lot of SSC articles are better than 400 pages books about the same subject.
