UNIT-I SOFTWARE PRODUCT AND PROCESS  SOFTWARE: software is a conceptual entity which is a set of computer programs, procedures,and associated documentation concerned with the operation of a data processing system. SOFTWARE USED IN DIFFERENT AREAS: 1.system software 2.real-time software 3.business software 4.engineering and scientific software 5.embedded software

LIFECYCLE MODELS 1.Waterfall model 2.Incremental process model  a)Incremental model  b)RAD model 3.Evolutionary process model a)prototyping b)spiral model

Waterfall model

INCREMENTAL MODEL

EVOLUTIONARY PROCESS MODEL (PROTOTYPING)

SPIRAL MODEL

Unit-II SOFTWARE REQUIREMENTS  Functional and non-functional requirements ( what the system should do? )  software document ( what is required of system develop ers?)  Requirement Engineering process ( create and maintaining requirement document )  Feasiblity studies ( does the system contribute to the overall objectives of the organisation ?)  software prototyping (Initial version used to demonstrate the concept)  Funtional and behavioral models ( Process of data )
