THE MASHWARE CHALLENGE: BRIDGING THE
GAP BETWEEN WEB DEVELOPMENT AND
SOFTWARE ENGINEERING- TOMMI MIKKONEN
ANTERO TAIVALSAARI
INTRODUCTION
The software industry is currently experiencing a
paradigm shift towards web based software.
 There is an impending mismatch between web
and software development
 Mashware software that leverages source code
and software components that are downloaded
dynamically from all over the world.
 The trend towards Mashware will aggravate the
gap between web and software development.

EVOLUTION OF THE WEB AS A SOFTWARE
PLATFORM



First phase: Simple page
structured documents
Second phase:
Increasingly interactive
with graphics, animation
and plug–in.
Recent trend is towards
desktop-style web
applications.
TOWARDS MASHWARE :WEB APPLICATIONS AS
MASHWARE
A mashup is a web site that
combines content from
multiple web sites into an
integrated experience.
 Allows unparalleled sharing
and reuse of software,
data, layout and
visualization information,
or any other content across
the planet.
This increases productivity
and reusability.

IMPLENDING MISMATCH

The principles and practices for web development evolved
rather independently of the principles and practices for
software engineering
INTERESTING RESEARCH AREAS:
Software engineering principle violations
 Usability and user interaction issues
 Networking and security issues
 Browser inoperability and incompatibility issues
 Development style and testing issues
 Deployment model changes
 Performance issues.

CALL FOR ACTION
So far, web engineering and software
engineering have evolved as separate fields.
 It is time to forget the origins of the browser as a
document viewing environment and to start
treating the Web as a real, full-fledged
application platform – one whose capabilities will
eventually far exceed those of the earlier
software platforms.

ULRICH STÄRK, LUTZ PRECHELT, ILIJA JOLEVSKI
WEB APPLICATION DEVELOPMENT PLATFORMS
“What is a Web Development Framework”
 Functions of Web application Framework
 Types of frameworks
 “What web framework should we use”

xkcd.com/292 by Randall Munroe
WEB DEVELOPMENT FRAMEWORK
Package to support construction of dynamic web
applications.
 Alleviating the repetitive overhead of
development patterns.
 Develop apps compatible with different
Browsers.
 More sophisticated, interactive, and wellmanaged

FEATURES OF A FRAMEWORK
Provide Core Functionality.
 Promote reusability and pluggability.
 Good at organizing large projects.
 Program actions and logic are separated from the
HTML, CSS and design files.
 Implement complex functionalities in efficient
manner.
 Enforce best coding practices.

DIFFERENT FRAMEWORKS CATEGORIZED
Model–view–controller (MVC)
 Push-based vs. pull-based
 Three-tier organization
 Content management systems

10 BEST FREE WEB APPLICATION FRAMEWORKS
Web Application Frameworks
Ruby on Rails
MVC ruby based framework geared for web application development
CodeIgniter
Powerful PHP framework with a very small footprint
Django
Python framework which encourages rapid development and clean design
CakePHP
MVC rapid application development framework for PHP
Zend Framework
Simple, straightforward, open-source software framework for PHP 5
Yii
High-performance component-based PHP framework
Pylons
Python web framework emphasizing flexibility and rapid development
Catalyst
Elegant MVC Web Application Framework
Symfony
Full-stack framework
TurboGears
Next generation TurboGears built on Pylons
PERFORMANCE COMPARISON
Speed and agility of building applications in Rails.
 ROR syntax is more cryptic than that of Perl.
 Python with Django combination yields high
performance.
 PHP with Symfony is the easiest language to code
in, has security issues.
 Java still chugging on Struts 1.X, JSF is promising.
Perl code tends to be small in size.
