A common problem among developers is an unwillingness to master the entire software stack. If you want great software, you must develop expertise in all layers including DB and OS.
Plus 1 to that. I am constantly amazed by otherwise smart people on both sides of one software divide or another that are unwilling to understand things that directly affect what they do, and in many cases software projects live or die by these decisions.
