Daniel Hutmacher has a nice web API to generate fake customer data:
I’ve been working on a little gadget for a while now, and today I finally got around to completing it and so now I’ve published it for everyone to try out. It’s a web API (wait, wait, don’t go away – it’s for database people!) that creates a randomized list of names, addresses, etc.
In this post, I’ll show you how easy it is to use this service to anonymize a development or test database so you don’t have all that personally identifiable information floating around.
Read the whole thing and check out his service. Also, Daniel was the one who spurred me on to update the theme here to get rid of some problems, so you can thank him for that too.
