This document is based on software engineering fundamentals. Author has explained on SDLC, Programming age and modes of software development! explaining software development life cycle and associated programming technologies. He explained modes of software development as well as programming paradigm is also illustrated. Phases involved on software development are also explained by the author. John Pereless is President / CEO of Pereless Software, a global software development firm delivering business solutions and custom applications to customers including National Geographic Channel, Fox, PepsiCo, and Nokia Siemens Networks. He is responsible for the strategic and overall business development of Pereless.

2. Basics Of Software
 As we all know the basics of software i.e. a well
written code or set of instructions that performs
specific task as intended in chunks of programs
coded in certain language so called programming
language. We are lifted above from the beginning
era of programming world. We’ve seen such zig-
zag and on track scenario on system
development life cycle. We achieved a lot from
the modern software age.

3. Contd..
 Software development is associated with the
computer programming, documenting the piece of
code, and testing involved in creating and maintaining
applications and frameworks i.e. platforms involved in
a software release life cycle and resulting in a
software product. The term refers to a process of
writing and maintaining the source code, but in a
broader sense of the term it includes all that is
involved between the conception of the desired
software through to the final manifestation of the
software, ideally in a planned and structured process.
Therefore, software development may include some
R & D to get new results as an outcome, new
development, prototyping, modification, reuse, re-
engineering, maintenance, or any other activities that
result in software products.

4. Goal
 Software can be developed for a variety of goals,
the three most common being to meet specific
needs of a specific client or business, to meet a
perceived need of some set of potential buyers or
users, or for fulfilling the personal need.
Embedded software development, that is, the
development of embedded software such as used
for controlling consumer products, such as inbuilt
firmware added on your devices such as washing
machines, printers internal controlling system,
your digital watch etc requires the development
process to be integrated or assembled with the
development of the controlled physical product.

5. SDLC & Processes
 The need for better quality control of the software
development process i.e. software development life
cycle has given rise to the discipline of software
engineering & reverse engineering at the same time,
which aims to apply the methodological systematic
approach exemplified in the engineering paradigm to
the process of software development. Software
testing plays a major role in releasing the software
versions. We can have this done in multiple phases
for various outcomes. But the ultimate goal of
software testing is to deliver a better version and fully
user friendly product that meets common goal of
achieving the results as well as zero bug identification
in terms of operating as well as security of the end

6. SDLC Steps
Analyzing the problem
 This phase is associated with identifying the
problem and understanding the actual business
or product goal. Analysis of involved users,
structure or prototype of product for the business.
Market research
 This phase involves market study for the product
to be developed. Product scope, competitive
market etc are analyzed and created a market
research report for further budget and marketing
mix analysis.

7. SDLC Steps
Gathering requirements for the proposed business
solution
 In this phase, software developer team ask for more
information on business i.e. what will be the business
plan? How the business will function? What will be the
business logic [Revenue model etc] How the users
will interact to the system? etc Once all information is
received, development team starts for the next phase
which is based on gathered information.
Devising a plan or design for the software-based
solution
 In this phase, the design prototype is sent to the
business owner or main business team for approval. If
things are modified, design team accept the changes
and work for further etc.

8. SDLC Steps
Implementation (coding) of the software
 This is very important phase as it involves the
software development programming
methodology. System is divided into various
modules and programming is done for the
individual module by the programming team.
Integration starts when module wise coding is
done.
Testing the software
 As we discussed above, in testing all bugs are
removed and the developed system is tested on
various parameters like speed, security,
functioning, operating etc

9. SDLC Steps
Deployment
 When the system is fully tested, approved by the
development as well as the business client end, it
is deployed for making it available for the end
users.
Maintenance and bug fixing
 This is the last phase on all SDLC and software
development model. Maintenance and bug fixing
is on going processes. The main goal of this
phase is to offer support services for
technological and structured changes.
