As with all books, there are chapters or sections that encapsulate really useful bits of information.
Such was the "recipe" called "Getting data from a database" in chapter 6, which compares the pros and cons (and when to use) of each of the 3 described DB access methods.
You basically nicely answered a question I had in the book, and saved the performance metering and thinking about suitability of each DB access method to real world use cases.
So - thanks!
