Chapter 4: Information System and Systems Analysis Quiz

Information Systems

• The purpose of software is to automate tasks, process data, and provide useful information to users.

Hardware and Data

• The term 'hardware' refers to the physical components of a computer system, such as the central processing unit, memory, and input/output devices.
• Data has four main characteristics: accuracy, completeness, consistency, and timeliness.

Management Information Systems (MIS)

• MIS stands for Management Information Systems, which provide routine, timely, and relevant information to managers to support operational and tactical decision-making.

Decision Support Systems (DSS)

• A Decision Support System (DSS) enables managers to analyze and evaluate different scenarios, create models, and make predictions to support strategic decision-making.

Difference between MIS and DSS

• MIS are used for operational and tactical decision-making, while DSS are used for strategic decision-making.

Executive Support Systems (ESS)

• An Executive Support System (ESS) is used by top-level executives to provide strategic information and support high-level decision-making.

Transaction Processing Systems (TPS)

• The purpose of a Transaction Processing System (TPS) is to process and record daily transactions, such as sales, purchases, and payments.

Information Systems Managers

• The role of information systems managers is to oversee the development, implementation, and maintenance of information systems.

Systems Maintenance

• The goal of systems maintenance is to ensure that information systems continue to meet changing business needs and are reliable, efficient, and effective.

Prototyping and Rapid Applications Development (RAD)

• Prototyping and RAD are used to quickly develop and test software applications, and to reduce development time and costs.
• Organizations use prototyping and RAD when they need to develop applications quickly, or when requirements are unclear or changing rapidly.

Knowledge Work Systems (KWSs)

• Knowledge Work Systems (KWSs) are designed to support knowledge workers, such as engineers, scientists, and consultants, who require specialized systems to perform complex tasks.

Office Automation Systems (OASs)

• The primary function of Office Automation Systems (OASs) is to automate office tasks, such as word processing, email, and scheduling.

Common Functions of Organizations

• The common functions of most organizations include sales, marketing, finance, human resources, and operations.

Qualifications for Systems Analysts

• Systems analysts require strong technical, analytical, and communication skills to design and implement information systems.

Information Systems Elements

• The parts of an information system include hardware, software, data, networks, and people.

Transaction Log Systems

• A transaction log system is used to keep records of events in organizations, such as sales, purchases, and payments.

Users of Information Systems

• Employees, managers, and customers are involved in information systems in just about every way.

Personal Computers

• The main purpose of personal computers in information systems is to provide users with a flexible and customizable tool for processing and analyzing data.

Data Workers and Knowledge Workers

• Data workers and knowledge workers can be distinguished by the type of tasks they perform, with data workers performing routine tasks and knowledge workers performing complex, non-routine tasks.

End User Understanding

• Competent end users need to understand the capabilities and limitations of information systems, as well as the rules or guidelines for using software, hardware, and data.

Security and Ethics

• The rules or guidelines for people to follow when using software, hardware, and data include security policies, data protection regulations, and ethical standards.

Computer Networks

• Computers work together to provide communication, collaboration, and information sharing in an organization.
