This is a system i made in about 4 days
Uses a custom xml Database that I created a Binary Search for
Was pretty happy about that

I'm probably going to rework it a bit and put all the php inside the actual database folder so It would be a simple include function to get all the functions and etc (much like java's import)
Also Plan to rework the database so that I can neatly pack away massive data as well as a SQL to XML conversion tool
I like XML more because...
1) it makes a hell of a lot more sense visually than SQL
-Nested information within information just makes sense to me. Attributes make sense to me. A giant table does not
2) Due to the fact it shares schema with HTML, I'll eventually find a use for DomDocument there also I'm sure
-Like making themes actually a complete HTML document with nothing in it (unlike wordpress <.<) and just inputting the appropiate data on the fly
Oracle also created a XML database framework that could go through hundreds of nodes very very quickly.
Unfortunately, I have no idea what the name of it is
But I saw it in a "birds of a feather" at Web 2.0 expo in think back in 2010
But for the most part this is meant to be touch screen and have a login system
So I still need to rework some of the kinks like Eliminating the use for a keyboard and making sure an admin can create simple users
Likewise the admin will be the only one who can create and remove tables
Need to be able to catagorize and place tables into size and locations
However, the Bones are done, just need to put in the meat
