3. 1. Today, PHP and MySQL are the most widely used
combination of open source technologies for Web
Application Development
2. In the presentation, we first discuss the various concepts
that form a base-line for the development of web-
technologies, followed by extensive focus on the specific
application namely the Python Script Generator (PSG)
3. In the discussion of the Python Script Generator, the
technologies that come into play behind the scenes are
covered so that viewers of this presentation are
acquainted with the knowledge to utilize the right
technology for the application they intend to create

5.  The AMP stack consists of:
 A -> Apache the web-server.
 M -> MySQL the database.
 P -> PHP the server-side scripting engine.
 There are several open-source AMP stacks readily available for
use such as:
 LAMP – Linux Apache MySQL PHP, Perl & Python
 WAMP – Windows Apache MySQL PHP
 MAMP – Mac Apache MySQL PHP
 XAMPP – Cross-platform Apache MySQL PHP Platform

6.  Free and open-source
 Maintained by the Apache Software Foundation
 Multi-platform & cross-platform support
 Good support in the form of mailing list and large
community of users
 Strong Default Configuration
 PHP has several inbuilt functions to perform query with
MySQL
 Ease of duplication of infrastructure on development
machine

8. 1. Storage, Retrieval, Management – Easy because database
allows users to store data in a logic format
2. Security – Database adds to security of the web-application as
database access includes secured authentication.
3. Independence – Data can be updated independently from the
content of the web-site as well as from independent locations
4. Scalability – If data grows exponentially, it can be handled
independently with respect to the web-site infrastructure.
Database can be scaled across servers by implementation of
several HDR options
5. Simple Integration – An existing database can be easily
integrated
6. Load Sharing – Database queries are processed autonomously
with respect to server-side scripts calling them, this decreases
load on the server-side scripts. Moreover, data retrieval from
database has been optimized over decades of data related
studies
7. Concurrency – Databases provide robust concurrent multi-user
access

9. Client-side script Server-side script
Processing Browser. Server.
Process Script is sent to the browser. Script is fetched from file system into the
server-side scripting engine
Load User's computer. Server machine.
Security Lower security because source-code
of the script can be exposed on the
user's computer.
Higher security because source-code is
interpreted and the resulting HTML is
returned to the user's computer (Logic is
secure).
Speed Very quick, because processing is
happening on user's computer
There is delay in fetching the processed
resource from the server.
Dependency User's browser needs to support the
client-side scripting language. It must
also be enabled for the web-
application to function smoothly.
The result of server-side script processing is
generally HTML which is supported on all
browsers.
Performance
Improvement
Performance can be improved by
increasing hard-disk/RAM of the user's
computer. There is performance
impact seen when the user opens
multiple web-application/web-pages
on the browser simultaneously.
Performance depends not only on server's
hard-disk, RAM and the Network but also on
simultaneous concurrent connections to the
server-side application.
Application Input-validation, user-interaction. Database or server-resource access
Example CSS, JavaScript, AJAX, VBScript PHP, ASP.Net, Ruby on Rails, JSP, Perl

https://www.google.co.in/webhp?hl=en&tab=ww
, into function calls with parameters:
Dispatch.run(https://www.google.co.in/webhp, hl=en, tab=ww)

16.  Test automation is a challenging yet important
field in Validation world
 An average validation engineer is not expected to
be expert in any of the programming languages
that can be used to create the scripts to
automate test execution
 The idea was to create a tool that can aid
validation engineers to generate scripts quickly
and efficiently without the need of being an
expert in the scripting language
 Common Python script errors were improper
indentations and spelling mistakes which were
reducing the performance of validation engineers

36.  Common standard of test-case script creation – a benchmark
tool
 web-application - available everywhere, no need to install
 It has eliminated the chances syntax errors such as spelling
mistakes and problematic indentations.
 It does not require a Python expert to create a test-case
script. This eliminates the need to train people in Python to
create the wrapper files.
 Updating library - now independent of script creation
 Fast
 Centralized repository of scripts

37.  Using AMP stack can help developers reduce the
application development time.
 The python code generator enabled rapid
development of test-case execution scripts
thereby reducing the duration of validation
cycle.
 In this project, no of scripts in library were ~800
where as scripts were ~4000
 This give domain experts more time to create
efficient & more generic scripts

38.  In this presentation, we discussed the concepts
which come into play during developing a web-
application
 Distinction between Client-side and Server-side
scripting
 Benefits of implementing a database with web-sites
 The advantages of AMP stack was also discussed,
where we saw why PHP worked so well with MySQL
