Thanks again for a great article, sorry to rehash old banter, but I have a quick question (probably more some clarification).

Based on the singleton theory if I were to call DBfactory::factory()->query(".."); from anywhere in my application, it would be referring to the one single instance that exists?

So if I'm following correctly, I could essentially call this from anywhere in my application (or any other class) in a similar fashion to a global variable?
