A web database allows storing and accessing data via the internet. It uses a client-server architecture with a web interface to connect to backend database servers. Large businesses rely on web databases to store customer information and make it accessible online. Web databases provide platform independence and standardization through their use of web technologies like HTML. Their future involves new technologies like NoSQL, Hadoop, universal memory and blockchain.

2.  What is Web Database?
 Why Web Database?
 Client/server architecture
 Web interface to database
 Communication protocol and web address
 Database driven web architecture
 Advantage and disadvantages of web DB
 Web Aplications
 Future of web DB

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.

10. Web interface provides attractive, even for
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
displays the linked document.

11. Client interacting with web server.
Step 1: The GET request.
11
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.

being a database guru or even a technical
person.
