Hi all,

Is there any software or tool for drawing ERD and DFD?

I just want something equivalent to MS Visio and I'm NOT going to link ERD to database.

I've tired Dia and really don't like it.
Heard about MySQL workbench but by the sound of it, it's ONLY for drawing ERDs and linking them with Database, right?

I just want something simple and useful for ERD and DFD (and some other SSADM diagrams).

Please, any suggestions are welcome :)

Thank you very much.

Regards,
GS

Could you elaborate why you don't like dia?

Perhaps you like kivio?: http://www.koffice.org/kivio/

Well, it looks like it's not completed yet.
Says on the page they're looking for volunteers "to make it ready for release".

It also states it's "tight integration to the Koffice applications".
I don't wanna use another Office package. I'm happy with OpenOffice.

Is there NO specialised diagram software on Ubuntu???

Something like MS Visio, Software Ideas Modeler and so on (Windows)?

Well, there's dia, but you still didn't tell us what's wrong with it - before that it's kind of guessing to propose alternatives.

Yes, sorry about that. I totally forgot to answer that question.

I tried using Dia but it's just not professional looking, you see. It's very ugly as well.

I feel like there should be something better out there.

The controls seem to be difficult as well.

For e.g. MS Visio is quite easy and user-friendly. I didn't feel lost since the very first time I used it.
There is another old application called SSADM Select. That one isn't hard to use either although it wasn't very user-friendly.

It's just Dia that I feel like something is missing.

So yeah, would be nice to use other good alternative that is user-friendly.

Thanks and regards,
GS

This one isn't bad, I quite like the Diagram drawing interface.

The only problem is the free account is a bit of rip-off.
It says you can have ONLY 25 sheets free and I was just looking around what diagrams they have and the drawing elements; that was counted as one sheet!!
I didn't even save it :S

I'm not prepared to pay for an account so this still isn't solution :|

Thanks for reply though.

I used Dia yesterday for good couple of hours because I really needed to draw some diagrams and you know what, it's not that bad actually.

Once you get passed its ugly plain look, it gets the job done.

Still, if there's any alternative I'd like to hear about it.
Just thought I'd share this since I changed my mind slightly :)

Many thanks and regards,
GS

I haven't actually tried any of this but in another context I found this link, http://www.lautman.net/mark/coo/index.html to enhance OOffice Draw.

Right, I have got 2 big problems with Dia.

One of them is annoying toolbox that is separated from the main window.

I have used Dia on Windows (although can't remember the version) and it was just ONE BIG WINDOW which is awesome!

But on Dia 0.97.1 Ubuntu, I can't seem to find the option that will make the toolbox combine with the drawing sheet.

Another problem is lack of Foreign key option when drawing ERDs.

Under attribute properties, there are "primary key" and "unique" options but NO FOREIGN key!!!

I've looked around and really cannot find anything.

Frankly speaking, this is pretty stupid. Anyone who does Relational Database would use both primary and foreign keys to link the tables.

So, at the moment, I have to put "FK" in front of every bloody foreign key which my lecturer isn't very happy about.

If any one knows how to resolve these issues, please help me out here.

I'm pretty much worn out from Googling and fiddling with this piece of ....

Thank you.

GS

Not sure if you found a solution yet. I agree with your assessment of Dia for making database diagrams. I love it for my equipment layout and cabling diagrams. However, for my database course, I used Open Office Database to create and diagram the database. Granted, I only had a very small diagram to do for the course, but it was quick and pretty. It might work for you!

you might also like LucidChart which is webbased.

don't be turn off by Kivio for its Koffice integration. Kivio works great as a standalone application. it was rock solid during KDE3 days. It took some time for its port to be completed in time for KDE4. but it must be just as solid now.

note that Koffice is now called http://www.calligra-suite.org/

It seems Kivio is still missing, or I cannot see it.

but getting the old Kivio is still worth it

Enterprise Architect?
Been a while since i used it, but it was really good. Not sure if there's a free version though.
