Asunto: Re: [ADMIN] open source ERD for postgresql database
This sort of depends on what you want to do with the ERD. If I want
to document an existing system, I use Aqua Data Studio. It's not
free, but it will take an existing system and draw the ERD for you
based on the relationships it finds in the database. There are
things that I don't like about it. It puts the tables into the ERD
in alpha order. This leads to some spaghetti ERD's. You can move
the tables around and then save them. The problem is that once they
are saved, it's an image and you can't move them anymore. If you
recreate the ERD you have to begin again to move the tables around.
Another tool that some people like, but that I haven't used is called
SQL-EZ. It's cost is trivial.
