This is just the stuff I've run into with a few hours work.

Supertypes/subtypes.  Creating a relation so a subtype does
not work in a suitable manner.  I ran into this last week, and don't
recall the details.  The solution was not to use super/sub types, 
though I would have preferred it.

Creating a FK relationship to table A from table B and C, where 
B and C have the same primary key.  I use PK for the primary
key on entities/tables, and assign the UID as an alternate key.

When trying to do this, ER doesn't do it properly.  It uses the same
attribute/column for the FK to both B and C.

Creating >1 relations between 2 tables using the same primary
key from the parent.  This is very common. ER doesn't like this.

I struggled with it a bit last week, don't yet have it resolved.

All of the above are quite easy in Oracle Designer.

I'll probably find more...

Ok, I'll bite.  Can you name a few Designer features that ER Studio is 
missing?

I have not used either product, I am stuck with an ancient version of 
ERwin.  Mgmt almost purchased ER Studio, but then the economy, and 
business, crashed...

No.

Though I'm not currently using Designer, I've worked with it quite a bit 
in the past for data modeling.  Don't use the autolayout.

I'm currently using Embarcadero ER Studio.  If Designer wasn't such a pig, 
I would have bought it instead, and am currently wishing I had anyway.

ER Studio is very fast, but not *nearly* the tool that Designer is.

Is there a way to make the autolayout feature produce a concise layout in 
Designer Entity Relationship Diagrammer?
