State Models - SENG-350-2024-fall/Team4 GitHub Wiki

The Nurse State Machine Diagram visually represents the various states a nurse can be in while interacting with the system, and the transitions between these states based on specific events or actions. This diagram illustrates how a nurse progresses from logging in to performing tasks such as reviewing triage results, scheduling follow-up appointments, updating patient information, and monitoring resources.

This diagram shows the process of logging in to Mister Ed. The process begins at the homepage, and when the user clicks "login" the system enters the login page state is entered. If incorrect login info is entered, the state stays the same. If the user chooses to sign up an account, the system switches to a sign-up screen after which the user is logged in with the new account, and if the user correctly enters login info the site grants access for the user.

This diagram shows the process of adding a new facility to the Mister Ed database. This is a linear process in which the system can move through the steps of adding a new facility (shown left-to-right), or cancel actions to return to a previous state (shown right-to-left).
