Package View

Primary Presentation

Front End Package

The Front End Package encapsulates everything which makes up the interface that users interact on the Mister Ed web app.

Element Name	Description
Pages	The webpages themselves, created using react.
States	Store important information of the user's session in the browser (logged in, account type).
API Clients	Communicate with the back end to submit and retrieve information.
Components	Shared elements and libraries used on all pages for functionality of the app (react router, material ui, navigate, etc).

Back End Package

The Back End Package is the behind the scenes engine that controls the creation, storage, retrieval, and modification of data relevant to the system. It is by and large the JSON server.

Element Name	Description
JSON Server	The back end which stores all of the Mister ED data. The db.json stores all user and triage information, while logs.json stores all the logger information generated during a user session for availability tactic purposes.

Data Layer Package

The Data Layer Package is a further abstraction of how the data within the JSON Server backend is represented in the system. The back end package is dependent on this abstraction and the data it contains.

Element Name	Description
Users	This covers all of the different types of users in the system, created by a common user factory pattern. Each has its own set of permissions and data values, and each is grouped by type.
Notifications	Dispatch requests and appointments. These objects exist separate from the other object types, but share similar behaviour in being generated during triage and notifying a third party user, the EMTs and Doctors, respectively.
Queue	Holds the generated triage objects until they are dequeued and processed by a nurse. Dynamically grows and shrinks as triage objects are created and processed by patients and nurses.

Variability Guide

The notification and triage queue objects are not yet finalized, so their representation in this view is subject to change.

Other Information

This view is a high level overview designed to convey the logical separation of the major components of the Mister Ed system on a macro level, so some granularity is lost in things like individual pages, API clients, database objects etc. It can be drilled down further by analyzing some of the other views.
