Introduction
In the given assessment of Collin’s car parking system there is three important use case of the
given system and then detailed use case of the selected use cases are build using the UML
language. Then the class diagram of the whole system is built describing the classes, objects, and
operation conducted by the specified class. Lastly, a sequence diagram of the given use cases is
built to show the timing behavior of the system.
Analysis of functionality:
Three important Use case:
Following are the three important use cases which can be used in the car parking system:
1. Enter the parking: In this use case, we will show the activities while entering the car
parking.
Figure 1: Use case for entering the parking
2. Payment mode: In this use case we will show that how the customer is paying to the in
charge.
Figure 2: Use case for payment mode

3. Exit the parking: In this use case, we will show the activities while exiting the car parking.
Figure 3: Use case for exit the car parking
Use case Diagram:
Use case diagram come under the UML. UML stands for unified modeling diagram which is
used to describe the system using the diagrams. Use case diagram is a diagram which indicates
the actions of the user and the relationship between the users and how they interact with each
other and also describes the system to accomplish the goal. There are various. In other words, we
can say that the use case diagram is used to show the interaction between the external actors &
the system to achieve the fixed goal. The system boundary is also defined by using the boxes.
Following are the elements which are used to make a use case diagram:
1. Actors: Actors are the users of the system who interacts with the system. Actors are the users
which interact with the system. A person, any organization, or external system can be an
actor which interacts with the system.
2. System: In the use case diagram, the functional requirement of the system is specified. The
system is divided into subsystem for the effective explanation of the system.
3. Goals: Goals are initiated by the users which are represented using the use case diagrams
which describe the activities & variants which are used to achieve that particular goal.
Basically, the result of the system is described as a goal (D'souza and Wills, 1998).
The actors are represented using a line with the caption action, the use case is represented using
the ovals and for showing the relationship between them the arrow line is drawn between the
actor and the activity. There is a box around the use case to describe the boundary of the system
(Sengupta and Bhattacharya, 2006).
