Are these Objects right? Heres the question that i identified them from (i am new to OOP), then after the question are what i think are the objects, if anyone could give me any pointers as to if ive messed anything up badly: A software system is required to control a security system. The system consists of an entry panel at each entrance, both external and room and corridors inside. The panels will be a mixture of a numeric keypad with an LED display and a card insert or a swipe card. Each panel controls entry through an electronically controlled door. A local controller can control up to ten entrances. A centralised controller maintains lists of users and the rooms (or zones) they currently occupy. This information is requested the local controller or periodically if an authorised member of staff requests it. Both the local and central controllers should be able to display who is in each room (or zone) at any particular time. For safety reasons there should be an override that will unlock all doors in the event of an emergency. Local controller overrides will unlock only the doors it controls, the central controller override will unlock all doors in the building. The system will receive information from the fire detection system and act accordingly. The system should automatically inform the emergency services (you can assume that the emergency services are capable of receiving the data) Objects: Security system Entry Panel Entrance Panels Local controller Centralised controller users Override Fire detection system Swipe card Keypad If anyone could tell me if i have done anything majorily wrong or missed anything really important off, thanks!

Override sounds more like an operation than a class, to me. Back to top Bill_Richie Guest Posted: Sat Nov 27, 2004 5:39 pm    Post subject: Re: OOP question. Are these Objects right? So would each one of these objects have there own class? or would several be grouped up to form a class? Back to top Joe Guest Posted: Sat Nov 27, 2004 6:36 pm    Post subject: Re: OOP question.

Quote: So would each one of these objects have there own class? or would several be grouped up to form a class? Mostly I'd say each will have their own class, but their might be some exceptions. The two different types of controllers indicate that their might be some shared functionality between the two that can be contained in a base class.
