Web Development..
Web development is when your site becomes
dynamic! Nowadays the web can be used for a lot more then you
think and we can use these technologies to develop web applications
for many purposes.
The most popular type of dynamic websites that
we develop these days use web enabled databases. By using a
database driven website, you can update, query and publish
information in a variety of ways. When someone clicks on a
web page whose content depends on the database, the web server
determines which elements are needed and then requests those
elements from the database. The required information is then
passed from the database to the web server and is displayed
on the web page. Any website or web application that is data-driven
will work in this way. The application in the web browser is
simply the front end interface to a database back end hosted
on a remote server.
Examples of Database Driven Websites...
Well you may not thnk it but the majority of
websites that you use today will use a database. For example
popular e-commerce website such as amazon, play.com,
and even ebay use databases.
Their database will hold all the information to the products
they have and when you search the site for a specific item
the web application simply searches the database for items
matchin the search criteria and displays the results on screen.
Advantages of Web Enabled Databases...
The advantages of using web enabled databases
are that they are much easier, they can be implemented
by the client so we are not needed to update the website, and
they can hold as much information as you require whether its
only a couple or a couple of thousand. The main advantage however
is that they are dynamic which means 'changing'. The database
can be updated in seconds and the new information is immediately
displayed within the corresponding web page.
