In the context of the Wagga Base Hospital's X-ray facility, a pertinent use case is "Patient Scheduling and X-ray Examination." This use case captures the process from a patient's appointment request through to the completion of the X-ray report. The actor initiating this process is the General Practitioner (GP), who requests an X-ray for a patient by providing a referral. The patient, serving as the primary actor in the subsequent steps, visits the hospital to schedule an appointment. During this interaction, the patient presents the appointment request, and the system or staff issue an appointment slip. When the patient arrives for their scheduled X-ray, they present this slip to the radiology staff, who then proceed with the X-ray procedure. Once completed, the radiologist prepares a report, which is then sent to the GP. This use case illustrates key interactions and data exchanges essential for understanding the system's requirements and workflow.

The diagram in Systems Analysis and Design in a Changing World, 5th Edition, Figure 6.9, depicts various system components and the relationships among them. The top five arrows above the thick dividing line typically represent the primary flows of data and control signals between actors and system components. These arrows may include, for example, the flow of user input data from an external actor to the system, the transfer of control signals from the system back to actors, or data flows between system modules. The arrows symbolize the direction and type of interaction or data exchange, such as user commands, requests, or responses, critical for understanding how information propagates through the system and how external and internal entities communicate.

In the class diagram representing the football coaching scenario, the key classes are Coach, Team, and Player. The Coach class has an attribute, e.g., name, and a one-to-one association with the Team class, indicating that each coach trains exactly one team. Conversely, each team is associated with exactly one coach, denoting a bidirectional 1..1 relationship. The Team class contains attributes such as teamName and a collection of Player objects, with a multiplicity of 24 on Player, indicating a fixed number of players per team. Additionally, Player contains a boolean attribute indicating whether they are a foreigner or Australian. This diagram models the constraints of one coach per team and the composition of the team with specific nationality attributes.

The term "Customer" typically refers to the individual or organization that purchases goods or services from a system. "Disable Account" is a process or feature allowing a system administrator to deactivate user accounts, preventing access while retaining account data for record-keeping. The diagram described is a class diagram, which illustrates the static structure of entities (classes) and their relationships. An example statement representing this diagram could be: "A customer has an account that can be enabled or disabled, and the system manages customer data and account status."

The analysis class diagram based on the provided scenario depicts classes such as Academic, Lecturer, Researcher, Course, and Student. The Academic class serves as a superclass with subclasses Lecturer and Researcher. A Lecturer is associated with 1 to 4 Course objects they teach, with a multiplicity constraint of 1..4 on the relationship. Each Course is linked to a single Lecturer, implying a 1..1 association. Students are associated with 1 to 4 Course objects, indicating their enrolled courses, with multiplicities of 1..4. The diagram emphasizes the hierarchical nature of academic roles and the many-to-many connection between students and courses.

From Systems Analysis and Design in a Changing World, 5th Edition, Figure 7.13, the diagram depicts the interactions among actors and system components in a sequence. It generally illustrates a scenario such as user login or data entry, the sequence of system responses, and the flow of events in temporal order. The actors initiate interactions, which trigger system processes, leading to specific outcomes like data validation, processing, and response display. The narrative describes each step, including inputs, system processing, and outputs, emphasizing the sequence and dependencies among actions, critical for designing and testing system behavior.

The Entity-Relationship diagrams are as follows: First, "A tree has many leaves" indicates a one-to-many relationship between the Tree and Leaf entities, with the Leaf entity belonging to only one tree. Second, "A car has one owner; an owner may own several cars" depicts a one-to-many relationship from Owner to Car. Third, "An author writes many books, and a book may be written by several authors" illustrates a many-to-many relationship between Author and Book entities. These diagrams help visualize database structures, showing entities, their attributes, and the nature of their relationships, including cardinality constraints.
