dynamic web pages?
To understand dynamic web pages you have to
understand normal web pages. Typical non-dynamic web pages do
not change every time the page is loaded into the browser, nor
do they change if a user clicks on a button. The only change
that you will see in static pages is to see them load and
unload, like what happens when you click on a hyper link.
In a nutshell: static web pages (normal pages
you build) always look the same and the content never changes
unless you load a new page or you change the page yourself and
upload the new version of the pages unto the server.
Dynamic pages do the opposite, they can
change every time they are loaded (without you having to make
those changes) and they can change their content based on what
user does, like clicking on some text or an image.
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.
Hopefully you are starting to see why you would
want a database driven site; you would want it if your
information changes very often, just like in a banking site.
Database driven sites can be built using several
competing technologies, each with its own advantages. Some of
those technologies/tools include:
