Indeed, but the subject matter of chapter 2 of the tutorial is more like
introduction to databases 099. Others may rightfully claim that
transactions and views are also elementary parts of database
application designs, but then there wouldn't be any advanced subjects
left.
I feel that there is a very useful dividing line between chapters 2 and
3: chapter 2 is about getting the data in and out, to give beginners a
feeling that the database system is working, chapter 3 is about
refining the data structures for higher convenience, maintainability,
and integrity -- "design".
