QUESTION 1 Q1 (a) Explain any four limitations of the architectural model which is used to design the data bases. [4] (b) Differentiate sub systems and modules in the context of architectural design with a suitable example system. [4] (c) Muscat Airport uses Traffic Monitoring and Control System (TMCS) to continuously monitor and regulate the flight traffic. It records various parameters like temperature, humidity, moisture using several sensors and also takes the details of number of flights in each track. Based on all these values, it issues control signals to the flights for landing and takeoff. (i) Recommend the most appropriate architectural model that can be used to represent the control flows between the different sub systems of TMCS with proper justifications. [5] (ii) Advise any three user interface (UI) design principles to be followed for designing the interface for the given system with proper justifications. [6] (iii) Advise any three most appropriate interface styles that can be used to design the user interfaces of the given system with appropriate reasons. [6]
