Absolutely nothing. Namespaces are for source code separation, not
database selection.

Let's say you have two different packages, each with:

class ExampleClass

Now if you include both packages in the same PHP file, you'll get a
parsing error for the second instance of ExampleClass.

So, you have two different namespaces. Put each one in its own
namespace and you can use both.

Think if it as an implicit prefix to everything defined within the
namespace.
