In the early days of the web, websites were mostly digital brochures. They were static HTML pages. You could read them, but you couldn't interact with them. If a business wanted to change a price, a developer had to manually edit code and re-upload the file via FTP.
It was slow, expensive, and didn't scale.
Then came the legendary LAMP stack (Linux, Apache, MySQL, PHP). Suddenly, the web became dynamic. The industry quickly realized that almost every business problem on earth;whether running a bank, an online store, or a social network,boiled down to four fundamental actions:
Create: Letting a user sign up or post a status.
Read: Showing a user their profile or a product list.
