How does a website communicate with database?
The application server can communicate only through the intermediary of a database driver. A database driver is software that acts like an interpreter between the application server and the database. After the driver establishes communication, the query is executed against the database and a recordset is created.

How does a database-driven web site work?
Usually database driven web sites have admin panel with user-friendly interface where you can manage the site content, i.e. add, edit, or delete info by yourself, create new pages or delete old ones. You can update your site easily each time you need it.
How is content read from a database in a website?
Users can register their details, then add content. When the user clicks the “Submit” button, their details/content is inserted into the database. Then when someone decides to view this content, it is read from the database using SQL (Structured Query Language). Some websites have a combination of static content and dynamic content.
Why does database take so long to download?
Many Web pages are constructed in their entirety by the Web server, including by PHP that accesses the database, and then sent to the browser all at once, so any database delays would lead to a long waiting time, and the receiving/downloading time would be proportional to the amount of data sent.
Why are web pages connected to the database?
The reason it is so called is because the ‘action’ or magic that allows the web pages to connect to the database is actually taking place on the server. This is what happens: each time a dynamic web page is about to be sent to the browser, the server automatically builds the page and sends a standard HTML page to the browser.
