[plug] E-R Diagramming tools

[Simon Scott]

Hi all

Just wanting to whip up an E-R diagram.

I have DIA and Kivio, but neither seems to have the type of elements I need. 
DIA has an ER set, but it doesnt correspond to my diagramming (classic style 
with rectanges for entities and forked lines showing relationships.

Does anyone know of a good tool for this, preferably one which will also let 
me enter the fields/keys and will show foreign key relationships?

Thanks
