3.  A web database is a system for storing and
displaying information that is accessible from
the Internet / web.
 A web database is a system for storing
information that can then be accessed via a
website.

4.  A web database is a database that can be queried
and/or updated through the World Wide Web
(WWW). As web technologies are evolving, the
WWW turned out to be the preferred medium for
many applications, e.g., e-commerce and digital
libraries. These applications use information that
is stored in huge databases and can only be
retrieved by issuing direct queries to the back-
end databases. Database-driven web sites have
their own interfaces and access forms that create
HTML pages on-the-fly. Web database
technologies define the way that these forms can
connect to and retrieve data from database
servers.

5.  Large businesses rely on databases to store
customer information. Because this
information is accessible wherever Internet
access is available, customers don't have to
go to a local banking branch, for example, to
access their account information.

database applications that are used only with
a single organization.
The HyperText Markup Language(HTML)
standard allows text to be neatly formatted ,
with important information highlighted.
Hyperlinks which are links to other
documents.Clicking the Hyperlink fetches and

Client interacting with web server.
Step 2: The HTTP response.

12.  Checking that the request is authorized
The server first responds by sending a line of text that indicates the
HTTP version, followed by a numeric code and a phrase
describing the status of the transaction. For example,
HTTP/1.1 200 OK
(Indicates success)
Whereas HTTP/1.1 404 Not found
informs the client that the web server could not locate the
requested resource.
