Who am I? I am not sure. But I have been in the IT industry for over 30 years. I have programmed in many different languages. Used SQL for most of my development life, again on many relational database platforms. I even once used an OO database and thought that was they way to go. It seems not! I have modelled many things using many products. Obviously I have modelled using OO and UML. I am trying my hand at Android Development because I think there are opportunities that still can be grasped. I guess you do too!
