driven by
- methodologies, techniques, and tools
- methodologies, techniques, and tools
- Application Software : Computer software designed
to support organizational functions or processes
- Systems Analyst : Organizational role
most responsible for analysis and design
of information systems
- System Development Methodology : is a standard
process followed in an organization to conduct all
the steps necessary to analyze, design, implement,
and maintain information systems.
- Systems Development Life Cycle (SDLC):
Traditional methodology used to develop,
maintain, and replace information systems.
- It is have 5 Phases : Planning , Analysis , Design ,
Implementation , Maintenance
- and have 2 views :
- standard view
- Evolutionary View

- Traditional Waterfall SDLC
- It have 3 Problems : 1- System requirements “locked
in”after being determined (can't change) 2- Limited
userinvolvement (only in requirements phase) 3-
Too muchfocus on milestone deadlines of SDLC
phases to the detriment of sound development

- Based on objects rather than data or processes , it is
constant of : Object , object class , Inheritance

- Rational Unified Process (RUP)
- An object-oriented systems development methodology it is have four phase of
development: inception, elaboration, construction, and transition.Each phase is
organized into a number of separate iterations.
