Unit 6 to Unit 7 Flashcards
These are purchased systems from outside vendors.
Software packages
This is a step-by-step process for developing high-quality information systems.
System Analysis and Design
This is someone who plans, develops, and maintains information systems.
System Analyst
What are the 3 business and information systems?
Brick-and-mortar
Click-and-mortar
Click
This refers to a traditional street-side business that offers products and services to its customers face-to-face in an office or store that the business owns or rents.
Brick-and-mortar
This is a type of business model that has both online and offline operations which typically includes a website and a physical store.
Click-and-mortar
These are companies who have a website/online presence without a physical store.
Click
What does e-commerce stand for?
Electronic commerce
What does I-commerce stand for?
Internet-commerce
What are the two sectors of e-commerce?
Business-to-consumer and Business-to-business
Differentiate b2c and b2b e-commerce.
Business to consumer involves consumers purchasing from a business through online shopping while business to business involves a business purchasing from another business.
This user strategizes plans.
Top manager
These users provide direction, necessary resources, and performance feedback to supervisors and team leaders.
Middle managers and knowledge workers
These users oversee employees and carry out day-to-day functions.
Supervisors and Team leaders
These uses include those who rely on TP systems to enter and receive data they need to perform their jobs.
Operational Employees
This is the process of defining, designing, testing and implementing a software application.
System development
What are the phases in the system development life cycle?
Planning
Analysis
Design
Implementation
Maintenance
This is the initial stage in the systems development life cycle (SDLC). It is the fundamental process of understanding why an information system should be built and determine how the project team will go about building it.
Planning
This stage involves analysis activities.
Analysis
This requires fact-finding to describe the current system.
Requirements modeling
This refer to necessary data that enters the system.
Input
This refer to system characteristics such as speed, volume, capacity, availability, and reliability.
Process
This refer to electronic or printed information produced by the system.
Output
This refers to the logical rules that are applied to transform the data into meaningful information.
Performance
This refers to hardware, software, and procedural controls that safeguard and
protect the system and its data from internal or external threats.
Security
This shows the steps that make up a business process, along with who’s responsible for each step.
Business flowchart
What does an oval represent in a flowchart?
Start or end point
What does an arrow represent in a flowchart?
connector that shows relationships between the shapes
What does a parallelogram represent in a flowchart?
Input or output
What does a rectangle represent in a flowchart?
Process
What does a diamond represent in a flowchart?
Decision
What are the 3 types of flowchart?
Document, system, program
This type of flowchart illustrates the flow of documents and information between areas of responsibility within an organization.
It is particularly useful in analyzing the adequacy of
control procedures.
Document flowchart
This flowchart depict the relationship among the input, processing,
and output of an AIS
System flowchart
This flowchart describes the specific logic to perform a process shown on a systems flowchart.
Program flowchart
These are statements that
describe what the system should do or possess to meet the needs of its users and stakeholders.
System requirements
What are the two types of system requirements?
Functional and non-functional requirements
These requirements describe what the system does.
Functional requirements
These requirements define the qualities that describe how the system should perform. It answers the question, “how well does the system perform?”
Non-functional requirements
This stage is the making of the physical design of the system that will meet the
specifications described in the system requirements document. It include
output and user interface design, data design, and system architecture.
Design
This is the method by which a prototype is developed. It involves a repetitive sequence of
analysis, design, modeling, and testing. It is a common technique that can be used to design
anything from a new home to a computer network.
Prototyping
This produces a full-featured, working model of the information system.
Because the model is “on track” for implementation, it is especially important to obtain
user feedback, and to be sure that the prototype meets all requirements of users and
management.
System prototyping
This is the method of development that employs
technical mechanisms for reducing risk in a project, when the project needs are vaguely
and poorly laid out. The end product of design prototyping is a user-approved model that
documents and benchmarks the features of the finished system.
Design prototyping
This is a functioning system but it is less efficient than a fully developed system.
Prototype
This describes how users interact with a computer system, and consists of all the hardware,
software, screens, menus, functions, output, and features that affect two-way communications
between the user and the computer.
User interface
This uses visual objects and techniques that allow users to communicate
effectively with the system.
Graphical User Interface
This allows users to send commands to the system.
Process-control system
This is how users communicate with the information system, and how the system supports the firm’s business operations.
User-centered systems
This describes the relationship between computers and people who use them to perform their jobs
Human-Computer Interaction
This phase begins once the client has tested and approved the system.
The system is installed at this phase to support the specified business functions. The performance
of the system is compared to the performance targets defined during the planning phase.
Systems Implementation
This is a continuous operation that includes eliminating
program and design flaws, updating documentation and test data, and updating user support.
Systems Maintenance
