System Analysis and Design - Complete Introductory Tutorial
for Software Engineering
Computers are fast becoming our way of life and
one cannot imagine life without computers in today’s world. You go to a
railway station for reservation, you want to web site a ticket for a cinema, you
go to a library, or you go to a bank, you will find computers at all places. Since
computers are used in every possible field today, it becomes an important issue
to understand and build these computerized systems in an effective way.
Building such systems is not an easy
process but requires certain skills and capabilities to
understand and follow a systematic procedure towards making
of any information system. For this, experts in the field
have devised various methodologies. Waterfall model is
one of the oldest methodologies. Later Prototype Model,
Object Oriented Model, Dynamic Systems Development Model,
and many other models became very popular for system development.
For anyone who is a part of this vast and growing Information
Technology industry, having basic understanding of the
development process is essential. For the students aspiring
to become professionals in the field a thorough knowledge
of these basic system development methodologies is very
important.
In this web site we have explored the concepts of system development.
The web site starts with the system concepts, making the reader understand what
does system mean in general and what are information systems in specific. The
web site then talks about the complete development process discussing the various
stages in the system development process. The different types of system development
methodologies, mentioned above, are also explained.
This tutorial is for beginners to System Analysis and Design (SAD)
Process. If you are new to computers and want to acquire knowledge about the process
of system development, then you will find useful information in this tutorial. This
tutorial is designed to explain various aspects of software development and different
techniques used for building the system. This tutorial is a good introductory guide
to the need and overall features of software engineering.
This tutorial is designed to introduce Software Engineering concepts
to the upcoming software professionals. It assumes that its reader does not know
anything about the system development process. However it is assumed that the
reader knows the basics of computers.
