Question
I'm looking for free tool for generating ER diagram. I now there are a lot of stuff I can find them in google, but I need something specific and can't it find.
The tool should generate ER diagrams showing relations between attributes like in below image. Note that this diagram shows phisical relation table1.attributeX <----> table2.attributeY
Note: I am not asking for tools that generate diagrams like these. This diagrams doesn't explicit show relations between attrobutes.

OTHER TIPS
As far as I know that's the style MS Access uses in their relationships dialog/overview. It is not the standard so I don't think there a lot of tools will support that kind of notation. I suggest to take a look at ms access. The alternative? I know that in DeZign for Databases you can drag the relationship line on a side of the entity box. This way you can manually point it to the correct attribute. Not sure if you want that.
