Title: How to denote a 'Composite Attribute' in EA?

How to denote a 'Composite Attribute' in EA?

For more details on a "Composite Attribute" please refer:
http://cs.anu.edu.au/student/comp3420/lecs/lec14/ClassesEntities_COMP3420.shtml


For example:

'Address' is an composite attribute of 'Student' class.

The 'Address' attribute has other simple attributes like 'Street', 'Town', 'City', 'State' and 'Zip'.

By definition, the components of a composite attribute are written underneath the name of the composite attribute and are indented to the right.

How to achieve this in EA?

Thanks in advance :)

Do you have any a priori suggestions as to how you might attempt to create such "composite attributes"?

Have you tried creating the appropriate code snippet and reverse engineering it?

Attempting to create the code snippet should lead you to the kinds of modelling constructs you will need to represent them...

BTW: I know how I represent "composite attributes", but your requirements may vary - particularly if the assignment has specific requirements...  ;)

HTH,
