SYSTEM SPECIFICATION
Given a "potential client", I designed a system that tracks sales and inventory and enables online shopping. In this academic paper, I specified the data of this system. The class diagram displays the different sections of data interacting with each other, the infrastructure diagram shows the system interacting with its environment, and the security plan demonstrates the possible security threats to the designed system.
CLASS DIAGRAM
​
The class diagram is a structured model that demonstrates the attributes, operations, classes, and relationships. The classes are the bigger boxes/rectangles, however the name of the class can be identified within the first section of the box. Below the name of the classes are the attributes, which represent the important characteristics of the classes. Under the attributes are the operations, and they represent the behaviors or methods of the classes. The lines that connect the different classes are called associations, which represents the relationships between classes.

INFRASTRUCTURE MODEL
​
This infrastructure model focuses on the system in its environment. Visual representations of the hardware and external systems and how they interact with the other systems around them are included. In this instance, the customers and employees will need to use a device that has access to the internet, and the data of the system will be stored in a database server. There are firewalls for security purposes, and the lines display the relationships between the software and hardware in this model.

SECURITY PLAN
​
The security plan describes any possible security threat to the system and the actions that should be taken in order to limit the danger of these threats. Even though there are some concerns about the hardware, the main concerns about security threats put the software of the system in danger. The chart demonstrates the various methods to reduce the damage of the possible hazards listed under the chart.
