Introduction
In this assignment report, the discussion will be made on the car parking system by Collin’s. The
parking system has a capacity to operate around the twenty cars in the city of Melbourne CBD.
There are two types of customers who use the service of this parking system as ordinary and
fixed. In this report, various sub system use case will be discussed for the car parking system.
Also, the sequence diagram is also given for each sub system to show the work flow or process
flow of the parking system for different types of customers. There is also class diagram and the
full use case diagram is given for the complete understanding of the parking system.

Types of diagram
A. Interaction diagram:
The interaction model is a model which can be used for defining objects which merged to
form single use case. The diagram defines objects & messages which pass among objects
in the use-case. The interaction model can be categorized into two categories i.e.
sequence diagram and collaboration diagram. The model is easy to understand and the
structure of interaction diagram is very simple. The one drawback of interaction diagram
is that it does not define the behavior.
B. Collaboration Diagram:
The collaboration diagram depicts various software objects communicate with each other
and also discuss about advantage of collaboration. It is combination of arcs and vertices.
C. Sequence Diagram:
The sequence model depicts the object connections which are arrange according to
sequence of activities. The class and objects are represented by sequence diagram. Loops
are presented by rectangle in sequence diagram. The diagram helps to visualize and
validates numerous scenarios. The synchronous messages sent in sequence diagram need
a response while in asynchronous diagram the user can continuously sent message
without waiting for any response. The messages are written above arrowheads.
D. Use case diagram: In use case diagram, there are actors and various use case to show the
system interaction with the customers. Actors are the defined person who uses the use
case. And the use case are the interactions that are the defined for some case (Shibboleth
Authentication Request, 2018).
