How it Works.
The Matrix is a file based XML database plugin and stores all data in the /data/other/matrix folder.
Each table consists of a folder for each table and an XML file for each record called id.xml where id is the record number of the file.
Tables can have an unlimited number of records or can be limited to a set number of records.
On first run you will have a single table created for you '_routes' this is a system table for the routing functions.
