XML Model mappings

Chapter 12 Creating Mappings

XML Model mappings

In an XML Model (XSM), you can create the following types of mappings to express generation dependencies or data transformation movement between model objects:

XML-to relational mapping between XML elements or complex types and PDM tables.
XML to object mapping between XML elements or complex types and OOM classes.
XML to XML mapping between XML elements or complex types and elements of another XSM.

The following table shows all the allowed mappings with XML Model (XSM) objects:

Target XSM object	Source PDM object	Source OOM object	Source XSM object
Element	Table, view, table column, view column	Class, class attribute	Element, complex type, element attribute
Element attribute	Column, view column	Class attribute	Element attribute, element
Complex type	Abstract data type	Class	Complex type, element
Complex type attribute	Abstract data type attribute	Class attribute	Complex type attribute, element attribute

Mapping elements

XML elements can also be mapped to the sub-objects of source objects, as an XML element can correspond to a simple type containing only an elementary value (for example <Name>Bill</Name>).
