Ø
A data model in the first sense is the set Ø
of constructs (complex types, simple types, Ø
element declarations, attribute declarations, Ø
etc.) defined in the XML Schema specification. Ø
A data model in the second sense is a particular
Ø
XML Schema. For example, the Geography Ø
Markup Language (GML) XML Schema is a Ø
data model in the second sense. Thank you Michael and Jim. As I look through the XML Schema specification I see no UML diagrams. As I look through the GML specification I see many UML diagrams. Are UML diagrams not relevant/useful for data models in the first sense? Are UML diagrams only relevant/useful for data models in the second sense?
