one interest question: does it make sense to build a worldwide database ?
some one asked me this question, and i am wondering if it's really needed to build one or wether this plan can be carried out effectively cause there are so many troubles, such as security, privacy, maintaince, costs, economic and political factors.
i think it's a big, however, interesting question! i need your help, and any reply is appreciated!
A lot depends on what you mean by "worldwide". Most of my databases are already worldwide in the sense that they have schema designs that support users with clients all over the world. I can't figure out any use for a database that would be actively used by the entire world... I can't imagine that any business or government would use it for anything.
