CompanyBackendServer is a flask back-end application written in Python 3. System tests written in Java and Python are also included. The demo server is hosted at https://shielded-bayou-99151.herokuapp.com, and includes a PostgreSQL database of its customer data along with its staff accounts. Functionality is exposed through the flask RESTful API.

How to use

frontend

• Navigate to the demo web app and login as user1 or user2 with the demo password blocktrace. You should be able to login if no other users are currently logged in.
• Click on refresh database, which sends an authenticated HTTP POST request to the CompanyBackendServer, and loads it in a heavily CSS-ed table.
• To remove a user from the company's database, click on the remove icon on the last column of each row. Confirmation will be requested as this process is non-reversible.

backend

• Host the flask server on something like Heroku. You can access the PostgreSQL database using the methods in the /Tests folder to create new staff users, and for debugging purposes.
