All Implemented Interfaces:

Configurable, Database
```
public class DatabaseImpl
extends SimpleDatabase
```
Reference Database implmentation. The reference Database simply resides on the file system. It isn't speedy but it serves the purpose of illustrating how a driver should work..
The path where the data files are located is specified through the property xmldb.data.dir. If this property is not specified it defaults to a directory named data in the current working directory. If the directory does not exist an attempt will be made to create it.
