UNIT - 1 : Introduction to SAD (System Analysis and Design) :
Q. What is a System ?
Ans : System is a word derived from the Greek word 'Systema' or (systēma, in turn from Greek σύστημα systēma, is a set of interacting or interdependent components forming an integrated whole).
In general, a system is based on Input ---> Process --> Optput (IPO model). Manual work can be replaced by computerized system for accuracy and speed of processing. Hence a standard Methodology must be considered. As there are many approaches available - so selecting the best approach is the responsibility of a SYSTEM ANALYST and this selection is based on the requirements of end user, problem definition and the infrastructure provided. Standard principles should be followed for the development of good quality software.
