Modeling Relational Database Objects Using UML

[Yarik]

The way EA models various RDB objects (tables, their indices and constraints, views, etc.) with UML - where exactly did it come from?  

Is there any sort of standard or recommendations on how RDB and UML concepts should/could be mapped to each other? Or is it completely homegrown by Sparxians?

The reason I am asking this is to understand exactly what is EA's freedom in how this modeling could work (and then suggest possible changes to how it works now).

Thank you,
Yarik.

There isn't an OMG ratified UML Profile for Data Modeling, so EA's data modeling functionality is based on a de facto standard which originated with IBM/Rational. A Google for "Data Modeling Profile" should find it.

I've found one suggestion of UML profile for datamodeling at http://www.agiledata.org/essays/umlDataModelingProfile.html

And In December 2005 the OMG issued an RFP for a UML data modeling profile. http://www.omg.org/cgi-bin/doc?ab/05-12-02
