What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.

3. Introduction and Web Development Strategies
World Wide Web:
The World Wide Web is a system of interlinked hypertext
documents accessed via the Internet. Web is a huge collection
of pages of information linked to each other around the globe.
History of WWW:
• WWW is created by Sir Tim Berners Lee in 1989 at CERN in
Geneva.
• In 1990, the first text only browsers were setup and CERN
scientist could access hypertext files and other information at
CERN. HTML was based on a subset of the standard
generalized markup language (SGML). To transfer HTML
document to remote sites a new protocol was devised called
HTTP (Hyper Text Transfer Protocol).
4. • In the fall of 1991, conference goes around the world
started hearing about the promise but sparks still
were not flying.
• In 1993, there are only about 50 websites world
wide. A browser that allowed user to take advantage
of the web’s graphical capabilities was developed at
the National center for Super Computing
application (NCSA). NCSA called the browser
Mosaic.
5. Protocols Governing Web
Protocol: A protocol is a set of rules that is used to
communicate applications to each other.
OR
A protocol is the interface required for communicating the
different applications.
Classification:
a. HTTP
b. TCP/IP
c. FTP
d. SMTP
e. TELNET
6. HTTP
HTTP: HTTP is the primary protocol used to distribute
information on the web.
Initial HTTP 0.9 does not allow for content typing and
does not have provisions for supplying meta-
information.
Content Typing: To identify the type of data being
transferred.
Meta Information: It is supplemental data, such as
environment variables that identify the client’s
computer
7. • TCP/IP: It is a set of rules that an application
can use to package its information for sending
across the networks of networks.
• FTP: It is used to transfer the files over
networks.
FTP uses TCP to create a virtual connection
for control information and then creates a
separate TCP connection for data transfers.
The control connection uses an image of the
TELNET protocol to exchange commands and
messages between hosts.
8. • Simple Mail Transfer Protocol (SMTP) is
an Internet standard for electronic mail (e-
mail) transmission across Internet
Protocol (IP) networks.
• Telnet: Telnet lets you remotely log into
another system and browse files and
directories on that remote system.
9. Website
A website is simply a collection of interlinked
web pages.
Classification:
A. Corporate Website
B. Individual website
10. Corporate Website
• In this, there is certain no. of persons, who
develop their website for a particular organization.
• The corporate website are formed when group of
people have common interest and objective.
• The purpose of this website is to convey the
information of organization to all over the world.
Individual website
It is just like profile management system. In this type of
website an individual wants to develop website for h-
projection, career growth etc.
11. Cyber Laws:
Cyber law is a term used to describe the legal issues
related to use of communication technology,
particularly “cyberspace” i.e. Internet.
Indian and International Cyber Law: Cyber Laws are
formed by the government to prevent the internet
crime. These crimes could be hacking, threat on
internet, denial of services etc. Cyberspace includes
computer, computer networks, internet data,
software etc.
12. • Data Protection and Privacy Law: This is due to the
nature of the internet and amount of information
that may be accessed through it, such legislation is
critical to protect the fundamental rights of privacy
of an individual.
• Electronic and Digital Signature Law: This is required
so that uniform and standard procedures are
established for authentication of electronics
records, EDI, E-Mail.
• Computer Crime Law: due to victim of internet
threats.
13. • Telecommunication Law: Approve and supervise the
application of fees and rates charged for
telecommunication services in accordance with the
provision of the applicable law.
• Intellectual Property Law: This includes copyright
law, trademark law, semiconductor law and patent
law in relation to computer hardware and software.
14. IT Act 2000 (INDIA):
In May 2000 ,both the houses of the Indian
Parliament passed the Information Technology
Bill. The Bill received the assent of the
president in August 2000 and came to be
known as the IT Act 2000.
Cyber Laws are contained in the IT Act 2000.
This law aims to provide for the legal framework
to all electronic records and other activities
carried out by electronic means.
15. Web Applications
• Web application is a kind of application that
can be through the web browser over the
internet.
• Web applications may include simple office
software word processors, Google docs,
project management, computer-aided design,
online spreadsheets, and presentation tools.
• Some common scripting languages are used to
create web applications such as JSP,ASP and
PHP.
16. • Web applications interact with program
variables ,spreadsheets and databases using
user input for creating the dynamic web
content.
• Some Examples are
a. Airline Reservation System.
b. Message Boards.
c. Shopping Cart.
d. Net-banking.
17. Writing web Projects
Developing web project is a crucial activity and web
project development differs from traditional web
projects
Phases of writing the web projects are
A. Write a project mission statement:
Write the specific mission statement that you want to do.
B. Identify Objectives:
i. Specific
ii. Measurable
iii. Attainable
iv. Realistic
v. Time limited
18. C. Identify your target users:
The matter of a website will be determined by the
users whom you want to visit the site. This is totally
depend upon
i. Market research
ii. Focus group
iii. Understanding the audiences
D. Determine the scope: By supporting documents
and client’s approval.
19. E. Budget:
i. Assumption for budgets.
ii. Budget categories.
iii. Determine hidden costs and tools.
F. Planning issues:
i. Discuss client’s existing information system.
ii. Project team and developing infrastructure.
iii. Where the website will place.
