Why Connect Web Pages to Data Sources?

Dynamic Content:
1. Unlike static websites, dynamic websites generate content on-the-fly.
2. This allows for features like user profiles, shopping carts, and live updates.
Personalization:
1. Data-driven websites can tailor content to individual users, enhancing the user experience.
Interactivity:
1. Features like forms, comments, and real-time notifications rely on data sources to function.

How Web Pages Connect to Data Sources

The connection between a web page and a data source typically involves three main components:

Client-Side: The user's browser, which displays the web page.
Server-Side: The web server, which processes requests and interacts with the data source.
Data Source: Usually a database or an API that stores and manages data.

Client-Side Requests

When a user interacts with a web page (e.g., submitting a form), the browser sends a request to the server.
This request is often made using HTTP methods like GET or POST.

Example

When you search for a product on an e-commerce site, your browser sends a GET request to the server, asking for products that match your query.

Server-Side Processing

Paywall

(on a website) an arrangement whereby access is restricted to users who have paid to subscribe to the site.
