This series covered the theoretical side of db change management quite well BUT didn't give me what I wanted.  I read all 4 parts looking for names of products, real world scenarios, etc and didn't find what I was looking for.  I'd like to see more practical "howto" instructions added to the series.  For instance:

How do you sequence the individual scripts into one larger build script (easily)?

What tools do you find work well and why?

What are the details of managing upgrade/ downgrade scripts in a VCS?

How do you automatically deduce a db version by looking at the spinning db?

The implementation section had one section that started to answer my questions.  Maybe the author could do a follow up or part 5?
