A lot of different data structures might be useful as indexes.

That's simply repeating yourself. You haven't proven your assertion and, in fact, you've contradicted it on several occasions.

You be sure to point them out and I'll address any I made, right after you provide some solid support for your claim that relations are the only data structure that should ever be used.

You can start with this one: "The database schema and the application logic change for different reasons. Decoupling the two minimizes the impact of those changes." Fredrik http://mybase.sf.net

Decoupling the two minimizes the impact of those changes." Nice, an easy one. As I said, I'll get right on it just as soon as you provide some solid support for your ridiculous assertion that relations are the only data structure that should ever be used.
