Hi SO.

I am learning a lot about design patterns these days. And I want to ask you about a design question that I can't find an answer to.

Currently I am building a little Chat-server using sockets, with multiple Clients. Currently I have three classes.

Person-class which holds information like nick, age and a Room-object.
Room-class which holds information like room-name, topic and a list of Persons currently in that room.
Hotel-class which have a list of Persons and a list of Rooms on the server.

I have made a diagram to illustrate it (Sorry for the big size!): http://i.imgur.com/Kpq6V.png

I have a list of players on the server in the Hotel-class because it would be nice to keep track of how many there are online right now (Without having to iterate through all of the rooms). The persons live in the Hotel-class because I would like to be able to search for a specific Person without searching the rooms.

Is this bad design? Is there another way of achieve it?

Thanks.

Do you need a good background in OOP before moving to frameworks?

Frameworks being all OOP, would it not be wise to go into frameworks without having a solid background in OOP? I can write basic classes but nothing too fancy or abstract. How much should I know of OOP before moving to frameworks? Right now I am PHP Object-Oriented Programming to learn OOP. >>> More
