Object Views vs. Nested Tables vs. Relational Tables

You now know three approaches of storing parent/child type of data: good old relational tables, nested tables, and object views on top of relational tables. Which ones should you use? Since this book is focused on performance, we will compare these three methods to see which ones fare better as far as performance goes. Intuitively, an approach based on relational tables should outperform the other two approaches. However, we still need to ascertain by approximately how much. Also, it would be interesting to know the difference in performance between the nested table–based approach and the object view–based approach, as they are more or less equivalent in functionality and expressiveness (once all the instead of triggers on the object view are in place).
