and an end, and that produces
a desired result or product

Front 2

phase

Back 2

related system development activities,
which are grouped into categories of
project planning, analysis, design, implementation,
and support

Front 3

systems development life
cycle (SDLC)

Back 3

a project management framework organized
into phases and activities

Front 4

planning phase

Back 4

the initial phase of the SDLC, whose
objective is to identify the scope of the
new system and plan the project

Front 5

analysis phase

Back 5

the phase of the SDLC whose objective
is to understand the user needs and
develop requirements

Front 6

problem domain

Back 6

the area of the user’s business for
which a system is being developed

Front 7

design phase

Back 7

the phase of the SDLC during which
the system and programs are designed

Front 8

application

Back 8

the portion of the new information system
that satisfies the user’s needs in
the problem domain

Front 9

implementation phase

Back 9

the phase of the SDLC during which
the new system is programmed and
installed

Front 10

support phase

Back 10

the phase of the SDLC whose objective
is to keep the system running productively
after it is installed

Front 11

help desk

Back 11

the availability of support staff to assist
users with any technical or processing
problem associated with an information
system

Front 12

comwaterfall
approach

Back 12

an approach to executing an SDLC in
which one phase leads (falls) sequentially
into the next phase

Front 13

incremental development

Back 13

a development approach that completes
parts of a system in one or more
iterations and puts them into operation
for users

Front 14

agreedsystem
development
methodology

Back 14

comprehensive guidelines to follow for
completing every activity in the systems
development life cycle, including
specific models, tools, and techniques

Front 15

model

Back 15

a representation of an important aspect
of the real world

Front 16

Tool

Back 16

software support that helps create
models or other components required
in the project

Front 17

CASE tool

Back 17

a computer-aided system engineering
tool designed to help a systems analyst
complete development tasks

Front 18

technique

Back 18

a collection of guidelines that help an
analyst complete a system development
activity or task

Front 19

structured approach

Back 19

system development using structured
analysis, structured design, and structured
programming techniques

Front 20

structured program

Back 20

a program or program module that has
one beginning and one ending, and for
which each step in the program execution
consists of sequence, decision, or
repetition constructs

Front 21

top-down programming

Back 21

dividing more complex programs into a
hierachy of program modules

Front 22

structured design

Back 22

a technique providing guidelines for
deciding what the set of programs
in an IS should be, what each program
should accomplish, and how the
programs should be organized into a
hierarchy

Front 23

structure chart

Back 23

a graphical model showing the hierarchy
of program modules produced by
the structured design technique

Front 24

structured analysis

Back 24

a technique that helps the developer
define what the system needs to do
(the processing requirements), what
data the system needs to store and use
(data requirements), what inputs and
outputs are needed, and how the functions
work together as a whole to accomplish
tasks

Front 25

data flow diagram (DFD)

Back 25

a graphical model showing the inputs,
processes, storage, and outputs of a
system produced in structured analysis

Front 26

entity-relationship diagram
(ERD)

Back 26

a graphical model of the data needed
by a system, including things about
which information is stored and the
relationships among them, produced
in structured analysis and information
engineering

Front 27

information engineering

Back 27

a traditional system development
methodology thought to be more rigorous
and complete than the structured
approach, because of its focus
on strategic planning, data modeling,
and automated tools

Front 28

object-oriented approach

Back 28

an approach to system development
that views an information system as a
collection of interacting objects that
work together to accomplish tasks

Front 29

object

Back 29

a thing in the computer system that
can respond to messages

Front 30

object-oriented analysis
(OOA)

Back 30

defining all of the types of objects that
do the work in the system and showing
what user interactions are required
to complete tasks

Front 31

object-oriented design
(OOD)

Back 31

defining all of the types of objects
necessary to communicate with people
and devices in the system, showing
how objects interact to complete
tasks, and refining the definition of
each type of object so it can be implemented
with a specific language or
environment

Front 32

object-oriented
programming (OOP)

Back 32

writing statements in a programming
language to define what each type of
object does, including the messages
that the objects send to each other

Front 33

class diagram

Back 33

a graphical model used in the objectoriented
approach to show all of the
classes of objects in the system

references that link the various
models together
