All Implemented Interfaces:

DataWriter
```
public class NativeDBDataWriter
extends AbstractDataWriter
```
The native database data writer persists the physical objects into a list of files in a database native loadable format. It keeps a static map to cache the information of the mapping from a table name to a command data. It is to make sure in the command file there will be no more than one command data for a single column. When the load item finishes, it should call clearTableCommandDataMap() to clear the cache.
