The Critical Components of a 
Database Web Application

Web Server

The web server hosts the application and processes user requests, managing user and database data interactions.

Front-end

The front-end is the user interface users interact with through web browsers. It is responsible for presenting data, accepting user inputs, and facilitating user interactions with the application. 

Back-end

The back-end consists of server-side scripts and processes that handle data storage, retrieval, and processing. It communicates with the database, executes queries, and processes data before sending it to the front end for presentation. Think of front and back development as web design vs web development (https://sonatafy.com/web-design-vs-web-development/).

Database

The database is the central repository where data is stored securely. It can be a relational database, such as MySQL or PostgreSQL, or a NoSQL database, like MongoDB.
