Data Mapper is a visual data-mapping tool used for mapping elements in advanced data integration projects. This tool allows you to specify source and target schemas and to map data fields from source schema to target schema.

You can use the Data Mapper tool to map source schema elements to target schema elements. You can map one source schema element to a target schema element directly by drag and drop method. Additionally, this tool also offers certain mapping functions using which you can map source and target schema elements.  Furthermore, the Data Mapper supports multiple source and target schemas. This implies that you can select more than one schema at a time, both at the source and the target end. This facilitates mapping of multiple source and target schema elements.
