Turning The Design Clock Back

Object-oriented design principles haven't had the effect we hoped for. The
SOLID principles are excellent design guidelines, but experience shows that
programmers find them difficult to follow. What do we do about this?
Surprisingly, the Structured Design literature of forty years ago contains
compelling solutions to many current design problems. They're simple and easy
to understand, but were lost in the noise as OO rose to popularity. We'll
reinterpret these simple design ideas in a modern context, finding that many of
our most promising new design ideas resemble them. Rapid web application
