Design Challenge 2

This project analyzes the user interface of a mobile phone application using UML diagrams, including use case diagrams, class diagrams, and activity diagrams, to illustrate the system's interaction with users and its internal data structure.

3. Analysing user interface to allow interaction with system
(a) Use case Diagram
(b)Importance of creating Use case diagram
This is used to describe different cases in which individual is involved. Here, the use case
diagram is used to show relationship of main entity with different situation. Mobile solution
company acts as actor which is involved in multiple situations. Basically this model is used to
describe that Mobile solution is a small consultancy company who want to design an online
mobile services application to facilitate in buying mobile phones easily (Gogolla and et.al.,
2017). Mobile Solution company provides the online phone and want to design an application in
order to facilitate buyers for easy transaction of buying phone. Here, this organisation is playing
the role of actor which is involved in different cases. This mobile solution application can be ale
to perform different use case such as online user login in order to purchase phone. Second case
depicts the details of product and third one will provide customer care facility to consumers for
resolving queries.

4. Data structure
(a) Class diagram
(b) Class diagram multiplicity
It can be considered as logical association of different classes which when combined with
different classes then methods can be used in performing multiplicity of roles (Gulia and
Choudhury, 2016). This is basically used so that one class can access the objects of another class
and it can be used for multiple function.
(c) Importance of creating class diagram
Purpose of class diagram is to present basic architecture of an application. Class diagram
can be generally used to depict object oriented language using the structured form of class in
order to create view about objects used in different classes. Here, mobile solution app is used to
perform various methods. Classes used in this model are mobile solution, user, payment method
and product. In these classes, multiple methods are used to call different objects of different
classes (Torre and et. al., 2018). Such methods are as follows login(), request(), make payment()
etc.

5. Determining system responding methods of Use case
(a) Activity diagram
(b) Importance of Activity diagram
It is used to describe various situational aspects of unified modelling language. This can
be represented using Flowchart structure (Knapp, Mossakowski and Roggenbach, 2015). It can
be considered as important flowchart because these activities and actions basically provide a
brief view about operations of system. Here, mobile solution app will be helpful in providing the
online phone services to customers and this diagram also contains feedback and customer care
features which facilitates users in resolving queries. Dynamic situations allow the user in
performing activities and actions (Grab CAD challenge, 2018).
