For a really long time, I've been using DBDesigner from FabForce.net.
For those of your who've never used it, its a freeware visual
entity-relationship diagram tool, which allows you to make database
designs visually instead of in SQL DDL. You can then use it to generate
the SQL to make your databse design into reality, or even run a
"synchronize" to make any changes you've made to the data model
reflected in the database.

Unfortunately, DBDesigner is no longer supported; I understand the
designers have went to work for MySQL on MySQL Workbench. I've been
limping along with DBDesigner for some time now, and then I discoverd
migrations.

I liked the functionality of migrations, but sure didn't want to give up
my pretty intereface. So, it occurred to me that I could write my own
for working with migrations.

WebERD (working title) is the result of that idea. It has a visual
database designer, using lovely AJAX and Scriptaculous stuff to make it
appear more like a desktop app. Currently, it will generate (somewhat
crippled) migrations from the schema you draw.

I've put a decent chunk of hours in on this project, and I'm at a point
where I'd like to see some feedback on what I've done so far. If you hop
over to http://test.bryanduxbury.com:8004 (textdrive proxy issues
there...), sign up for an account (please use your email address as the
login), and create a project, I'd appreciate what you all have to say
about the app.

Feature suggestions will be duly considered, and bug reports would be
great. It's still pretty rough, but I'm pleased with how well it works
for as long as I've worked on it so far.

One caveat: for some reason, the app doesn't work in Firefox. When an
AJAX call is made, Firefox actually crashes. If anyone could suggest a
path to follow to fix this problem, that'd be swell.

Thanks,

Bryan D.

it also crashes Kazehakase, built against Mozilla 1.7.13. i dont have an
answer for this. maybe try #firefox on freenode. im sure they want to
debug their javascript engine (maybe check out the nightly builds of
firefox 3.0 and see if its fixed first)

Thanks for the trace. However, how does one "try #firefox on freenode"?
I'm a bit of a noob when it comes to IRC.

Anyways, there's 39 people signed up, lots of project, etc, but only one
comment? Some of you must be using IE, right?

Firefox here. No crashes, but the table builder didn't really work.
Nothing visible happens. Exiting and re-displaying a project shows the
change but positioning is way off and none of the editing features work.

Ok, I managed to get through the crashes of my Firefox by upgrading. I
spent a couple hours making all the bugs that showed up in Firefox go
away, and now it works. Check it out.

Looks like a fun idea Bryan. Unfortunately I can't get it to work in
either safari, firefox or IE5 on OSX.  I get to the design page and
see the menu at the top but nothing happens and I can't click
anything. What am I supposed to see. Does this only run in IE on
windows?

Nice effort, Bryan. I was able to create/edit one table but nothing
after that. I was IE6, but it was giving me problems with FireFox as
well. I could also create the migrations file. It looks pretty cool.
Keep up the good work, and I am sure it will be a very helpful tool.

Thanks,

Gave it a shot. Looks like there are some display issues to be
adressed. Firefox is not rendering anything on the design page.

I got around the Firefox crashing issue by upgrading to the latest
Firefox.

I haven't tested my app on a Mac yet, so I can't comment on how well it
would work there.

My next effort on the app will be to add more significant instructions
so you guys can actually find your way around.

Slightly off topic, anyone know a good javascript dropdown menu system?
