Question of remote sql connection with Titanium

Hi

I got several questions with Database connection with Titanium.

I try to connect mySql db and I found some examples which are connect with php page, but I wonder that the pages need to publish if I want to connect DB via php?

Furthermore, as I mention that I am using mySql, but one of my project guy made up DB for our project, so the DB is remote condition. In this condition, still above way(php bridge) is working or I need to use other way to connect. Please tell me or link me a useful links.

Thanks!
