Now a day’s all websites, web pages are dynamic. It means that it’s not just a page where in you read the data. You have multiple options on the page. Multiple tabs, check boxes, buttons that lead to some other data not already on the screen. All of this data shown and possibly shown on the website is basically stored in a data base. So whenever someone types in a website’s name in the address bar, the data base server pushes the home screen data. When you write a simple blog, that blog is stored in the database. When someone wants to read the blog, the blog is retrieved from the database. The comments posted on the blog are also stored in the database, only to be retrieved later on.
