DB Designer had a lot of bugs but one outstanding feature was that database models were saved in plain XML by default.
This allowed a user to diff file versions via SVN or Beyond Compare, easily finding any changes made to the database.
Unfortunately, DB Designer's succsssor, MySQL Workbench, stores files in a proprietary MVW file format, which is unreadable.
Is it possible to force MySQL Workbench to save as XML?
回答1:
No, the current version (5.2.10 beta) does not support that.
However, the file format is not proprietary - its a simple zip archive. It contains a single XML document which is the complete database model. I wrote this SO question a couple of months ago with the same goal as you seem to have. I wanted to be able to do svn diff model.mwb
The answer I got there helped me write a small script which unzipped the file before passing it to the diff tool. It worked decently and if you're interested I can post it somewhere.
I also very recently started a thread on the Workbench forum about this issue. Hopefully someone on the development team can provide some more input on this.
EDIT: it is now being tracked by MySQL Bug #51203 with a target of 6.0.
