1) Are there competing UML Data Modeling profiles (for relational
databases) or is only one being considered? One of Scott's articles
mentions that an
official data modeling profile RFP appeared at OMG in December, 2005.
It is now
~3.5 years later. Where does that stand:

2) If there's only one being considered, how far away are we from it
becoming an accepted standard?

3) How are UML modeling tool vendors handling this absence of a
standard, accepted data modeling profile? Will vendors create
transforms to the standard from whatever UML data modeling profile(s)
they currently support?

4) What precisely *is* an RFP? Is the OMG simply in a mode where it
is
soliciting entire candidate UML data modeling profiles, or has it put
out a draft of one profile and is asking for refinements / comments?
Or does that come later--RFC? If it's the former, how many years might
one expect a standard to selected, refined, and
ratified--and does this matter a whit to practitioners who have work
to get done?

5) What can the community do to accelerate the process of getting a
UML Data Modeling profile ratified? Does one have to be a prof or in
the upper echelons of one's field, or can "ordinary" professionals
contribute?

Of course there's the also question of an "impedance mismatch" between
a data-centric ERD-based and an app-centric / "unified" / OOP UML-
based approach to data modeling:

Thanks.

Mmm...This sounds as homework...

Frankly, who cares? It's not like UML has any theory behind it. It's
just yet another convention for drawing pretty pictures, and a crutch
best avoided.

UML was an empty fad of the early 00s. Currently almost nobody cares

Database design is more than vague drawings, but both drawing
conventions were very similar.
