Question$1$:

Consider that you are required to develop a mobile application

which aims at teaching young kids $(3-5$ years$)$ the Arabic

alphabets in an interactive and attractive way that encourages

kids to learn. When the child opens the application, he$/$she sees a

list of all Arabic letters presented in a graphical nice way. When

the child touches a letter, another page is opened where the

following functionalities are provided:

An image of the letter is displayed

An image of an objects that its name starts with the

letter is displayed

When the child touches the letter the sound of the letter

is played

When the child touches the object, the name of that

object is played

For the graphical user interface and for the interaction

design, a user centered approach should be followed to

achieve user satisfaction among targeted kids to encourage

them to learn. The plan is to provide the facilities to teach

numbers. For the future, the application should be extended

to work on additional platforms like a smart board and a

tablet. Moreover, tutorials for learning Numbers should be

added. Based on the above assumption please answer the

following questions:

a$.$ What Architecture Pattern will you use for this

system? Justify your answer $(2$ points$)$

b$.$ Draw a component diagram for the system guided by

the architecture pattern that you have selected $(2$

points$)$
