UML class diagram metamodel

Question

Where can I find a simplified class diagram metamodel ? It's for a ATL ATLAS Transformation Language project, I need to transform a entity class diagram to SQL database. thank you .

Answer 1

We (I´m now leading the atlanmod team, creator of the ATL language) have a "zoo of metamodels" with more than 200 metamodels in different formats, including ecore ones ready to use with ATL.

In fact we also have an ATL Transformation zoo with more than 100 ATL transformations you can experiment with (and learn from)

Answer 2

Here's a simplified class diagram metamodel, based on EMOF.

Answer 3

You could test MOSKitt (www.moskitt.org), modeling software kitt based on eclipse where you could find different modules including a transformation from UML Class diagram to Database using ATL and SQL code generation to different technologies (postgre, mysql, etc)
