2. WHAT IS ENGINEERING?
 The productive use of scientfic knowledge is
called engineering.
OR
 Using of systematic approach to develop a
product called engineering.

3. WHAT IS SOFTWARE?
 Computer programs and associated
documentation
 Software products may be developed for a
particular customer or may be developed for a
general market
 Software products may be
• Generic - developed to be sold to a range of
different customers
• Bespoke (custom) - developed for a single
customer according to their specification

4. WHAT IS SOFTWARE ENGINEERING?
 Software engineering is an engineering discipline
which is concerned with all aspects of software
production
 Software engineers should adopt a systematic and
organised approach to their work and use
appropriate tools and techniques depending on the
problem to be solved, the development constraints
and the resources available

5. WEB ENGINEERING
 What is Websit?
“A collection of logically connected Web pages
managed as a single entity.”
 What is webpage?
A single page developed in HTML, DHTML, CSS,
PHP……
 The term “Web engineering” was first published
in 1996 in a conference paper by
Gellersen.

6. DEFINATION
“The use of scientific, engineering, and
management principles and systematic
approaches with the aim of successfully
developing, deploying and maintaining high
quality Web-based systems and applications”.
The web engineering is_specialization_of
software engineering.

7. APPLICATION OF WEBSITE
Web has three type of application
1. Web hypermedia
• Non conventional e.g. HTML, JAVA SCRIPT,
AND multimedia .
• Publication of information on the web
1. Web software application
• Conventional ..egg. Ecommerce, data base
Booking system.
