One of the most common types of dynamic web pages is the database driven type. This means that you have a web page that grabs information from a database (the web page is connected to the database by programming,) and inserts that information into the web page each time it is loaded.

If the information stored in the database changes, the web page connected to the database will also change accordingly (and automatically,) without human intervention.

This is commonly seen on online banking sites where you can log in (by entering your user name and password) and check out your bank account balance. Your bank account information is stored in a database and has been connected to the web page with programming thus enabling you to see your banking information.

Imagine if the web page holding your banking information had to be built traditionally (that is by hand,) every time your bank balance changed! Even a thousand monkeys working 24/7 drinking 5 cups of coffee a day, would not be able to keep up!
