I've just published a walkthrough for datagenerator here. It should help in figuring out what datagenerator is capable of. This will probably be the way I publish all documents in the future...

I've fixed a few minor issues with the build I put up last night. The new release has a build number to enable you to more easily track what's new. I also fixed a minor bug with the environment variables in the windows build.

I've just uploaded datagenerator 0.3 to the downloads page. Its a big step forward. Apart from being multithreaded and generally much faster it includes a wizard that allows you to reverse engineer a schema... currently it only reverse engineers the tables and primary keys but I'll include more functionality over time. I've used it to build vey large schemas for the order entry benchmark much faster than I was perviously able to. In the next couple of days I'll post a script and instruction on how to do this.. In the mean time enjoy
