I believe that with this post you have proven yourself to be ignorant. You appear to not have a clue about how relational data is used in applications, nor does it appear that you can distinguish between a distributed database and an application. Perhaps you should consider keeping your mouth closed, unless, of course, you enjoy the taste of your feet.
