A dimension data converter modifies information before it is loaded in your data warehouse dimension tables. The data warehouse loader server invokes converter components if one is specified for a data warehouse repository item in the DimensionProperties.xml file for a product.

Dimension converters implement the atg.reporting.datawarehouse.process.DimensionConverter interface. This interface expects only a single method called convert to be implemented. Oracle ATG Web Commerce includes several dimension converters. You can modify these converters or develop your own if needed.

For example, the following warehouse-property element specifies that the data warehouse loader server should invoke the ProductParentCategoryConverter dimension data converter when loading a product repository item into a data warehouse repository item. The conversion-component attribute of the warehouse-property element names the dimension converter.

<warehouse-property
  name="parentCategory"
  conversion-component="/atg/reporting/datawarehouse/process/
                        converter/ProductParentCategoryConverter">

  <production-property
    name="catalog.product"
    conversion-context-name="product"/>

</warehouse-property>
