The ORM Foundation

 Is there any way around it? I am trying to convert an ORM model into a UML, and It seems that I have  ran into a situation similar to the one described on page 404 " Information Modeling and Data Base Design", Second Editon. Where the attribute itself has its own attributes, is there any way around it except to attach a note on the UML diagram?

 The workaround I use is to create a class for the attribute. For the example on p. 404, create a class called PersonTitle and give it an attribute called "value" or "text" to record the actual title, and add another attribute called "restrictedGender" then add a textual constraint (e.g. in OCL) to capture the constraint expressed in ORM as a join subset constraint. 

I know this is an ugly workaround, but at least it works.

Thank you so much, yes it is ugly but I will do that,
