WEB APPLICATION FOR HOSPITAL-VENDOR CREDENTIALISING

AVA ORG is a Hospital - Vendor medical device management portal, where the Vendor is a medical device manufacturer who publishes their respective products on the portal. Hospital representatives register themselves, browse published medical device products, and can contact vendors for buying the product. Also, they can add their requests for any unpublished/ unavailable medical devices. Vendors can explore these hospital requests and can connect with them for the production of specified devices. Hospitals will have to take into consideration the time required for the vendor to deliver the product. This project acts as a proof of concept.

TECHNICAL DESCRIPTION

The landing page of the web application is the homepage.html which displays images and texts loaded by the Python flask framework and jinja template. The data is fetched from the backend Azure SQL database using the python pyodbc module. The home page has the below navigations:

Home
Products
OnDemand Requests
About Us
Login/Register

Each navigation is associated with respective flask API routing.

homepage.html:

This HTML page is specifically available for unauthorized guests below limited options. We used CSS and Jinja template representations to design the HTML page. The interface has been designed to match an unauthorized view and feel that a guest user shall have. This page showcases the latest six products that get added to the database. Each product displayed has a link that will route the user to the individual product page, with a better view and further detailing about the product. All the data displayed on this page is fetched from the backend database every time the page is loaded.

user_homepage.html:

This is the authorized counterpart of homepage.html with further navigation accessibility.

products.html:

A guest user can view the available products and access each product separately.

new_products.html:

Authorized users will have an additional navigation option on the products.html page, which takes the user to create a new product via the provided form. Post form submission new entry is added to the database using the python "/New_Products" API.

about_us.html:

This page highlights the aim of the project.

login.html:

It shows fields to enter credentials. As for new users, the sign-up button is provided for registration at the bottom.

registration.html:

This page loads a form with two options to either select vendor or hospital based on which the below fields toggle. Javascript embedded ensures this toggling feature. There are validations set on the password field to ensure a strong password is accepted.Credentials.xml stores the credentials of registered users.

on_demand_request.html:

It is a page showcasing on-demand requests raised for products that are unavailable on the products page. Users can view the listed requests and access each request separately. Only authorized users are allowed to view this page.

new_request_form.html:

Authorized users will have an additional navigation option on the on_demand_request.html page, which takes the user to create a new request via the provided form. Post form submission new entry is added to the database using the python "/New_Request" API.

user_profile.html:

For authorized users, the page shows the user profile information. This page allows users to edit the details of their profile. There is an option to delete the account.

Azure SQL:

Created Azure SQL DB which includes tables - namely, hospital, vendor, product, product_images and ondemand_request to manage data inserted via the registration form, new product form, and new request form.

Azure App Services:

Hosted the application on Azure app services using zip package method deployed via powershell commands.

CONTRIBUTION REPORT

@Anirudh-Chandran

Primarily, the contribution has been focused on Python coding. A connection to the database required learning the PyODBC module. The initial connection and execution of commands took a day or two to establish. After successfully connecting, the main concern was determining how to work with Flask. Flask has been another challenging domain to work on; a lot of examples and tutorials were referred to during the development phase. The HTML pages that were created by the members had to communicate with Flask, and the required inputs and outputs had to be taken and provided to the webpage. There were efforts made to get the right format and kind of content. It had been a beautiful journey exploring the flask session, from confusions about whether the handling was happening or not to ensuring the correct session was handled. There were comparatively small efforts put into working with Jinja templates on HTML pages and firing the right SQL commands. XML templates were used to handle the credentials, for which some research had to be done.

@Ameya-Khandekar

Throughout the project, the main focus was on researching, developing and administering a database on Azure, as well as producing HTML webpages and designing them with CSS. Due to the fact that HTML and CSS had not been extensively utilized for a long time, substantial research and practice were necessary. To attain the desired objectives, several prototype webpages were built for practice and to guarantee that the final selected web pages were enough. CSS was used to format and style webpages in order to make them seem more presentable. JavaScript was also used to aid with certain development.

@vicky-motwani

Worked on HTML, CSS, JavaScript, designing SQL tables, and Azure app services.
Invested time and effort as follows:
HTML, CSS - Explored many web portals, designed a layout and theme, and applied it to HTML pages.
JavaScript - Implemented JavaScript for controlling field behaviour on the "My Profile" page.
Azure SQL - Researched, discussed, finalized, and created tables on Azure SQL; hence, it was accessible online for all members to collaborate fruitfully.
Azure app services - Researched hosting a web application on Azure and after exploring other unsuccessful methods, deployed our app on azure app services by uploading a zip package containing app files using PowerShell cmdlets.
