LEARNING UNIT 1: CHAPTER 1AN OVERVIEW
WHAT IS THE PURPOSE OF THE SYSTEM DEVELOPMENT LIFE
CYCLE (SDLC)?
It provides a framework, including methodologies, models, tools, and techniques, to build
and deploy an information system. Its purpose is to provide structure and organization to
the development process.
WHAT IS THE DIFFERENCE BETWEEN AN INFORMATION SYSTEM
AND A COMPUTER APPLICATION?
Usually, a computer application is a single computer program that may or may not be
connected to a database. An information system is normally multiple computer programs
that are connected to a database and thus provide as output various types and quantities of
information.
Computer application(app): a computer software program that executes on a computing device to
carry out a specific set of functions.
o Modest scope
Information system: a set of interrelated components that collects, processes, stores, and provides
as output the information needed to complete business tasks.
o Boarder in scope than “app”
o Includes database and related manual processes
System analysis: those activities that enable a person to understand and specify what a system
