The web app you are using is a demonstration of a tool that was built for a health system's supply chain team in 2021. This demo app was built to serve as a point of reference and to help visualize and explain how this process works.
The scenario that this demo app portrays is the following. You are a supply chain director for a local hospital. Every week on Sunday night, the backend of the production tool generates a list of five items that the system's algorithm has deemed to be held in excess of what your historical demand has shown. You find an email in your inbox telling you that there are five new items for you to review and reset. You then follow the link on the email to this site where you can start resetting your inventory levels on the "Reset" tab.
The version of this app that is in production uses a backend API that is written in Python using the Django Rest Framework. Data is saved using a PostgreSQL cluster which is managed by AWS. The frontend client is very similiar to the demo app you are using right now. It is a Single Page Application using the React library with state management using Redux. To help simplify the demo app, it is disconnected from a backend and is maintaining all data within the client using Redux. Simply refresh the browser to start over.
