II. Familiar Problems Solving
Objectives: This part aims to evaluate that you have some basic knowledge of the key aspects of the lecture
material and can attempt to solve familiar problems.
Question 2 (9 marks)
Consider the Course Registration Problem Statement:
The registration process works as follows: Students send an application form containing their personal
details and their desired course The University checks that the course is available and that the student
has necessary academic qualifications. If the course is available the student is enrolled in the course,
and the university confirms the enrolment by sending a confirmation letter to the student. If the course
is unavailable the student receives a rejection letter.
1- Choose the suitable software architecture style, justify your choice. (2 marks)
2- What are the ccomponents of the architecture? (2 marks)
3- Specify the connectors and its types. (2 marks)
4- Draw Software Architecture Style. (3 marks)
Question 3
(8 marks – 2 Marks for each)
A- For the following software architecture model determine (Components, Connectors, and Topology)
B- Consider the following diagram:
1- Specify the software architectural style.
2- What are the properties of the specified style?

Unfamiliar Problems Solving
Objective: This part aims to evaluate that you have some basic knowledge of the key aspects of the lecture
material and can attempt to solve unfamiliar problems.
Question 4 (8 marks)
The following concerns a simplified system of an airplane flight simulator for a video game
system:
“The video game system has already been implemented and consists of a computer with joystick
and pushbutton inputs and an output interface for a colour television. Your job is to develop the
software for the computer to display the view from the cockpit of an airplane. The joystick and
pushbutton control the airplane. The display should be based on a terrain description stored in
memory.”
Use Object-Oriented Software Architecture Style specifies:
a) Components (objects). (2 marks)
b) Connectors (messages and method invocations). (2 marks)
c) Draw Software Architecture Style. (4 marks)
