I know this kind of questions sound silly most of the times, but still I need to ask it. I am planning to get a web application done, for my business usage; it should be able to handle a huge DB scenario ( think of retailers DB ), support Mobile access as well.
I asked different developers, some advises PHP+MySQL+Apache are the best and cheaper to implement , Others insisted that ASP.net+Oracle/MSSQLserver is a must for the complexity of requirements and the scale.
I am lost between the two parties, without enough technical background to take the decision, which apparently would cost money and time.
As a 3rd party reviewer and professional web developers; please advice me.
