Web applications differ from conventional software in several key ways:
- Web apps are accessed through browsers and do not require installation, allowing cross-platform use. Updates are automatically applied to all users.
- They have limitations on system resources and depend entirely on browsers. High-end programs generally perform better as desktop apps.
- Areas of difference between web and software development include technologies used, quality approaches, stakeholders, architectures, and legal issues due to global accessibility of web apps.

QUALITY ASSURANCE AND INTEGRATION TESTING ASPECTS IN WEB BASED APPLICATIONSIJCSEA Journal
Integration testing is one the important phase in software testing life cycle (STLC). With the fast growth of internet and web services, web-based applications are also growing rapidly and their importance and complexity is also increasing. Heterogeneous and diverse nature of distributed components, applications, along with their multi-platform support and cooperativeness make these applications more complex and swiftly increasing in their size. Quality assurance of these applications is becoming more crucial and important. Testing is one of the key processes to achieve and ensure the quality of these software or Webbased products. There are many testing challenges involved in Web-based applications. But most importantly integration is the most critical testing associated with Web-based applications. There are number of challenging factors involved in integration testing efforts. These factors have almost 70 percent to 80 percent impact on overall quality of Web-based applications. In software industry different kind of testing approaches are used by practitioners to solve the issues associated with integration which are due
to ever increasing complexities of Web-based applications.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Web Engineering - Web Applications versus Conventional Software
1. Web Applications Versus Conventional Software
By Nosheen Qamar
University of Lahore, Pakistan
2. Web Applications Versus Conventional Software
Web Application Advantages over Desktop Application
Web Application Disadvantages over Desktop Application
Web Development Versus Software Development
◦ Application characteristics
◦ Primary technologies used
◦ Approach to quality delivered
◦ Development process drivers
◦ Availability of the application
◦ Customers (stakeholders)
◦ Update rate (maintenance cycles)
◦ People involved in development
◦ Architecture and network
◦ Disciplines involved
◦ Legal, social and ethical issues
◦ Information structuring and design
3. Web Application
◦ A Web application (Web app) is an application
program that is stored on a remote server and
delivered over the Internet through a browser
interface.
Conventional Software/General Software
◦ Software is a general term for the various kinds of
programs used to operate computers and related
devices. Desktop Application also considered as
Conventional Software.
4. Since they run inside web browsers, developers do not
need to develop web apps for multiple platforms. For
example, a single application that runs in Chrome will
work on both Windows and OS X. Developers do not need
to distribute software updates to users when the web app
is updated. By updating the application on the server, all
users have access to the updated version.
A web app may provide a more consistent user
interface across multiple platforms because the
appearance is dependent on the browser rather than the
operating system.
The data you enter into a web app is processed and saved
remotely. This allows you to access the same data from
multiple devices, rather than transferring files between
computer systems.
5. They do not run directly from the operating
system, they have limited access to system
resources, such as the CPU, memory, and the file
system. Therefore, high-end programs, such as
video production and other media apps generally
perform better as desktop applications.
Web apps are also entirely dependent on the web
browser. If your browser crashes, for example,
you may lose your unsaved progress. Also,
browser updates may cause incompatibilities
with web apps, creating unexpected issues.
6. To Identify differences between Web and software
development there are 12 areas, which are as follows:
◦ Application characteristics
◦ Primary technologies used
◦ Approach to quality delivered
◦ Development process drivers
◦ Availability of the application
◦ Customers (stakeholders)
◦ Update rate (maintenance cycles)
◦ People involved in development
◦ Architecture and network
◦ Disciplines involved
◦ Legal, social and ethical issues
◦ Information structuring and design
7. Application Characteristics Web applications are created by
integrating numerous distinct elements, such as multimedia files
(e.g., audio, video, 3D objects), HTML/SGML/XML files, graphical
images, mixtures of HTML and programs, and databases.
Components may be integrated in many different ways and
present different quality attributes.
In addition, their source code may be proprietary or unavailable,
and may reside on and/or be executed from different remote
computers. Web applications are, for the large part, platform-
independent and Web browsers in general provide similar user
interfaces with similar functionality, freeing users from having to
learn distinct interfaces.
Finally, a noticeable difference between Web applications and
conventional software applications is in the use of navigational
structures. Web applications use a hypermedia paradigm where
content is structured and presented using hyperlinks.
Navigational structures may also need to be
8. Web applications are developed using a wide range of
diverse technologies, such as the many flavoured Java
solutions (Java servlets, Enterprise JavaBeans, applets, and
JavaServer Pages), HTML, JavaScript, XML, UML, databases
and much more.
In addition, there is an increasing use of third-party
components and middleware. Since Web technology is an
area that changes quickly, some authors suggest it may be
difficult for developers and organizations to keep up with
what is currently available.
The primary technology used to develop conventional
software applications is mostly represented by object-
oriented methods, generators and languages, relational
databases, and CASE tools. The pace with which new
technologies are proposed is slower than that for Web
applications.
9. The quality is the principal factor that brings
repeated business. For Web development, quality is
often considered a higher priority than time to
market, with the mantra “later and better” as the
mission statement for Web companies who wish to
remain competitive.
Within the context of conventional software
development, software contractors are often paid for
their delivered application regardless of its quality.
Return on investment is immediate. Ironically, they
are also often paid for fixing defects in the delivered
application, where these failures principally exist
because the developer did not test the application
thoroughly.
10. The dominant development process drivers
for Web companies have three quality criteria
◦ Reliability
◦ Usability
◦ Security
followed by:
Availability
Scalability
Maintainability
time to market
11. Customers who use the Web expect
applications to be operational throughout the
whole year (24/7/365). Any downtime, no
matter how short, can be detrimental.
Except for a few application domains (e.g.,
security, safety critical, military, banking)
customers of conventional software
applications do not expect these applications
to be available 24/7/365.
12. Web applications can be developed for use within the boundaries
of a single organization (intranet), a number of organizations
(extranets) or for use by people anywhere in the world.
The implications are that stakeholders may come from a wide
range of groups where some may be clearly identified (e.g.,
employees within an organization) and some may remain
unknown, which is often the case.
To handle this Web developers are regularly faced with the
challenges.
Whenever stakeholders are unknown it is difficult to estimate the
number of users an application will service, so applications must
also be scalable.
In conventional software applications, it is usual for stakeholders
be explicitly identified prior to development.
13. Web applications are updated frequently
without specific releases and with
maintenance cycles of days or even hours.
In addition, their content and functionality
may also change significantly from one
moment to another.
The maintenance cycle for conventional
software applications complies with a more
rigorous process.
14. Web applications can be created by
◦ Artists (Graphic Designers, Web Designers, Micromedia Experts
etc.)
◦ Writers (Content Writers, Blog Writers, Creative Writers)
◦ Coders (Simple HTML code or many commercially available
Libraries, Plateforms or Web authoring tools like Macromedia
Dreamweaver, Microsoft Frontpage etc.)
◦ Web Developers/Programmers
◦ Librarians (To use online libraries)
◦ Database Designers/Administrators
◦ Project managers
◦ Network security experts,
◦ Test/Usability experts.
Conversely, the development of conventional software
remains dominated by IT professionals, where a sound
knowledge of programming, database design, and project
management is necessary.
15. Web applications are typically developed using a
simple client–server architecture (two-tier),
represented by Web browsers on client
computers connecting to a Web server hosting
the Web application, to more sophisticated
configurations such as three-tier or even n-tier
architectures.
Conventional software applications either run in
isolation on a client machine or use a two-tier
architecture whenever applications use data from
database systems installed on a separate server.
16. A team of people with a wide range of skills and
expertise in different areas (Software
Engineering, Hypermedia Engineering,
Requirement Engineering, Information
Engineering, Graphic design, network
management) is required to develop large and
complex Web applications adequately.
Building a conventional software application
involves contributions from a smaller number of
disciplines, these include software engineering,
requirements engineering and usability
engineering.
17. The Web as a distributed environment enables a
vast amount of structured (e.g., database
records) and unstructured (e.g., text, images,
audio) content to be easily available to a
multitude of users worldwide. So there is chance
of dishonest actions, such as copying content
from Web applications without acknowledging
the source, distributing information about
customers without their consent, infringing
copyright and intellectual property rights, and
even, in some instances, identity theft.
Conventional software applications also share a
similar fate to that of Web applications, although
to a smaller extent.
18. As previously mentioned, Web applications have structured and
unstructured content.
In addition, the design of a Web application, unlike that of
conventional software applications, includes the organization of
content into navigational structures by means of hyperlinks.
These structures provide users with easily navigable Web
applications. Well-designed applications should allow for
suitable navigation structures, as well as the structuring of
content.
Another difference between Web and conventional applications is
that Web applications often contain a variety of specific file
formats for multimedia content (e.g., graphics, sound and
animation). These files must be integrated into any current
configuration management system, and need to be organized.
Conventional software applications present structured content
that uses file or database systems.
