Pereless Software Software Engineering By John Pereless
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. Weve seen such zig- zag and on track
scenario on system development life cycle. We achieved a lot from
the modern software age.
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.
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.
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
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.
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.
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
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.
