This document discusses web engineering and compares it to software engineering. It defines web engineering as using scientific and engineering principles to successfully develop, deploy, and maintain high-quality web-based systems and applications. The document notes that web engineering is a specialization of software engineering. It also outlines several key differences between web development and traditional software development, such as the intrinsic characteristics of web applications, the technologies used, and the audiences they are developed for.
Introduction to WEB engineering TERMINOLOGIES
- 1. PRESENTATION CHAPTER#1 WEB engineering Department: Software Engineering University of Malakand [email protected]
- 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.
- 8. APPLICATION OF WEBSITE 3) Web application It combine both characteristics of web hyper media and web software..
- 9. WEB DEVELOPMENT VS. SOFTWARE DEVELOPMENT Main three differences 1. Intrinsic characteristics of web application. 2. Involved people. 3. Audience for which they are developed.
- 10. DIFFERENCES BASED ON THE ABOVE THREE CATEGORIES. 1.Application Characteristics 2. Primary Technologies Used 3. Approach to Quality Delivered 4. Development Process Drivers 5. Availability of the Application 6. Customers (Stakeholders)
- 11. NEXT 7. Update Rate (Maintenance Cycles) 8. People Involved in Development 9. Architecture and Network 10. Disciplines Involved 11. Legal, Social, and Ethical Issue 12. Information Structuring and Design
