Xml Data Source

simple xml data source to be used as a replacement to sql server for a poor

Project Description
The framework will be used for creating easy and simple xml data source to be used as a replacement to sql server for a poor, simple, non-complicated environment. All Access to the data is done via simple sql queries as "select" "insert" "update" and "delete". All queries are executed with simplistic assumptions and best try to return results without any exceptions.
