Software, databases and tree structured file formats!

Looking at disk Io for databases, I begin to investigate all the paing structures databases have available to manage disk data. Generally, database data is organized as trees of data, rather then linear arrangements,. Trees make for short traversals down the database.

What is my point?
What the industry really needs is a set of tree testers, a standalone program that can take a variety of trees and test their functionality against data sets. If I started a new project, that would be the target, making it easier for new data base engine designers to try and test various tree structures.

This is where my programming addiction starts. I think, hey, a few lines of code and I can try out one or two trees from this selection. I am getting better at resisting, however.
