Systems Analysis and Design (Midterms) Flashcards
(59 cards)
____________________ is a step-by-step process for developing high-quality information systems.
System Analysis and Design
_______________ combines technology, people, and data to provide support for business functions.
Information System
E-commerce between two companies uses a data-sharing arrangement called _____________ which enabled computer-to-computer data transfer, usually over private telecommunications lines.
Electronic Data Interchange
A _________________ is an overview of a company’s mission, functions, organization, products, services, customers,
suppliers, competitors, constraints, and future direction.
Business Profile
A _________________ is a specific set of transactions, events, and results that can be described and documented.
Business Process
___________________ refers to information systems that support company-wide operations and data management
requirements.
Enterprise Computing
_________________ are systems that can analyze transactional data, generate information needed to manage
and control business processes, and provide information that leads to better decision making.
Business Support Systems
Top managers develop long-range plans, called ______________, which define the company’s overall mission and goals.
Strategic Plans
________________ is the process of planning, scheduling, monitoring, controlling, and reporting upon the
development of an information system.
Project Management
The _______________ is conducted to evaluate an IT-related business opportunity or problem.
Preliminary Investigation
The complex organizational process whereby computer-based information systems are
developed and maintained.
Information Systems
Analysis and Design
Computer software designed to support organizational functions or processes.
Application Software
The organization role most responsible for the analysis and design of information
systems.
Systems Analyst
A standard process followed in an organization to conduct all the steps necessary to
analyze, design, implement, and maintain information systems.
Systems Development
Methodology
The traditional methodology used to develop, maintain, and replace information systems.
Systems Development Life
Cycle (SDLC)
The first phase of SDLC in which an organization’s total information system needs are identified, analyzed, prioritized, and arranged.
Planning
The second phase of the SDLC in which system requirements are studied and structured.
Analysis
The third phase of the SDLC in which the description of the recommended solution is
converted into logical and then physical system specifications
Design
The part of the design phase of the SDLC in which all functional features of the system
chosen for development are described independently of any computer platform.
Logical Design
The part of the design phase of the SDLC in which the logical specifications of the system
from logical design are transformed into technology-specific details from which all
programming and system construction can be accomplished.
Physical Design
The fourth phase of the SDLC in which the information system is coded, tested, installed,
and supported in the organization.
Implementation
Software tools that provide automated support for some portion of the systems
development process.
Computer-aided Software Engineering (CASE) Tools
Systems development methodology created to radically decrease the time needed to
design and implement information systems. This methodology relies on extensive user
involvement, prototyping, integrated CASE tools, and code generators.
Rapid Application
Development (RAD)
Systems development methodologies and techniques based on objects rather than data
or processes.
Object-oriented Analysis
and Design (OOAD)
