I would like to know how hosted eCommerce sites like www.shopify.com, www.3dCart.com etc.. automatically creates new sites when new users sign up. What kind of tools do they use to create those sites into the users profile. I have tried googling but couldn't find an answer.
Does any of you guys have any knowledge or experience that you can share with me? Or do you know a tutorial that you can point me to?
I hope my question is clear.
Thanks for your help.
