For
example, let's say you are the business owner of a used car lot.
You can use a web integrated database of cars, and store each car's
make, model, year, mileage, color, extras, and price.
A web user will be able to browse to your page, and search for Honda
Accords from '92 to '95, under $12,000. The search engine can return
a vehicle if make contains Honda, model contains Accord, year is
between 92 and 95, and price is less than 12000.
Your
database can include pictures, if you like, and links too. . When
you want to make changes to the database, just open up the page
created by the installer called [database name] admin.html. It will
prompt you for a password; the maintenance page looks just like
the user search page. To add a new entry, simply type the attributes
in the appropriate boxes and click 'ADD'. For example, let's say
we just got a new Toyota Camry in, and we want to add it to the
database.
If
I want to make changes to an entry, or delete an entry, I will search
for the entry, then click on the entry in the search results window.
Using our example, let's say we wanted to drop the price on the
'96 Toyota Camry from $14,500 to $13,500. Then, simply click on
the entry you wish to modify or delete
A
database driven web application must include the ability to modify
and delete listings as well. When you click on an entry, the modification
window opens for that entry. This is also where I would click delete
if the car sold, and I wished to remove the entry from the database.
In our example, I can now change the price to $13,500 and click
'MODIFY'.
That's
it! If you can use a web browser, you can maintain a web integrated
database site.
