Hotel Management System

Hi Everybody,
Have you heard about the course Hotel Management. Well, now hotel management students pass out and then Manage Hotels (hotels, restaurants, etc.).
Now, wouldn't it be better if you had a proper Hotel Management System (HMS) Online which the hotels can use to take their orders, keep track of expenses and more... now the problem for this is that hotel managers don't know programming and the programmers don't know hotel management. now i'll tell you more about how this idea came to me...
As You all know, or maybe not... i had gone to Dubai a few days ago. It was a great place and is know for the hotels. But this idea did not come when i was sitting in my hotel room and thinking about what to do here. This idea came to me when i had gone out to a South Indian Restaurant and saw, that the waiters were taking down there orders on an handheld device which according to me only had the order taking system... But what I am talking about is much more than that.
Now I am a programmer and i don't know the H in Hotel Management and what they do there. Anshul uncle always keeps talking about the course he went through so i'll try to approach him on this idea.

Thank You,
