UTA INSY 2303 EXAM 3 REVIEW, WITH
COMPLETE SOLUTION
Critical Path
The sequence of stages determining the minimum time needed for an operation
especially when analyzed on a computer for a large organization
Colocation Center
Centers that dedicate information systems which several corporations lease space and
equipment
Data Center
a specialized facility designed to hold and protect computer systems and data
Application Development Tool
Software that assists in the creation of new software
ERP
Enterprise Resource Planning; it is a suite of software modules that integrate major
business activities
SDLC/Phases of the SDLC
An information system progresses through several phases as it is developed, used, and
retired
order of phases
Analysis > Design > Implementation > Maintenance > Planning
main purpose
System Requirements Report > Application Specifications > Working System > Project
Development Plan
Feature Creep
A tendency for product or project requirements to increase during development beyond
those originally foreseen
JAD
Joint Application Design, A process used in the life cycle area of the dynamic systems
development method to collect business requirements while developing new information
systems for a company
BI
A technology driven process for analyzing data and presenting actionable information to
help executives, managers and other corporate end users make informed business
decisions
Object-Oriented Methodology
treats an information system as a collection of objects that interact to accomplish tasks
UML
Unified Modeling Language, The current standard for object-oriented documentation
class diagram
provides the name of each object, a list of each object's attributes, a list of methods, and
an indication of the associations between objects
use case diagram
documents the users of an information system and the functions they perform
, Sequence Diagram
depicts the detailed sequence of interactions that take place for a use case
System Conversion
the process of deactivating an old information system and activating a new one
Unit Testing
Each application module is completed undergoes this to ensure that it operates reliably
and correctly
Integration Testing
Performed to ensure that the modules operate together correctly
System Testing
Ensures that all the hardware and software components work together
MRP
Material Requirements Planning, A production planning, scheduling, and inventory
control system used to manage manufacturing processes.
Data Flow Diagram
The core documentation tool for project teams using structured methodology,
graphically illustrates how data moves through an information system
Success Factors
They also serve as an evaluation checklist at the end of a project
Gantt Chart
shows the duration of development tasks as they occur over time
WBS - Work breakdown structure
Work breakdown structure, breaks a complete task into a series of subtasks
PERT -Program evaluation and review technique
Program evaluation and review technique, used for analyzing the time needed to
complete each project task
JIT - Just-In-Time manufacturing
A methodology aimed primarily at reducing times within production system as well as
response times from suppliers and to customers
Horizontal Market
Designed for common elements of many businesses
Vertical Market
Designed for a specific industry or enterprise
Turnkey System
A computer system that has been customized for a particular application
B2B and B2G
Websites such as FedBid, Oracle, & Ingram sell goods and services to other
businesses or to the government
B2C (business-to-consumer)
Online storefronts such as Zappos, Amazon & Dell offer merchandise and services to
consumers
C2C (consumer-to-consumer)
Consumers sell to each other at popular auction and list sites, such as eBay & TaoBao.
Fuzzy Logic
An expert system can deal with this type of data by working with confidence levels.
These systems are designed to deal with data that is imprecise or problematic
