Overview

The WebSphere Commerce Loader package consists primarily of command utilities for preparing and loading data into a WebSphere Commerce database. You can use the Loader package to load large amounts of data and to update data in your WebSphere Commerce database.
The Loader command utility in this package uses valid and well-formed XML as input to load data into the database. Elements of the XML document map to table names in the database, and element attributes map to columns.
The Loader command utilities allow you to do the following:

Transform data between a character-delimited variable format and an XML data format.
Transform XML data into alternate XML formats.
Generate a DTD based on the target database.
Generate identifiers for XML elements.
Load data into the WebSphere Commerce database.
Extract data from a database as an XML document.
