Study Notes

Information System

An information system is a collection of components that collect, process, store, and disseminate information.
Information systems provide feedback to meet a specified objective.
Information systems can help businesses achieve their goals, increase revenue, and reduce costs.

Information Concepts

Information is a valuable resource for organizations.
Information uses data to provide meaning and context.

Data, Information, and Knowledge

Data consists of unorganized facts, information is organized data that has value, and knowledge is the understanding and application of that information.
Data can be transformed into information through processing.
Processing includes calculations, sorting, filtering, and summarizing.
Knowledge is the understanding and application of information, using it to make decisions and solve problems.

Characteristics of Valuable Information

Accuracy: Information must be free from errors and inconsistencies.
Completeness: Information should include all the relevant facts and details.
Consistency: Information should be consistent with other data sources and with organizational standards.
Timeliness: Information should be available when it is needed and up to date.
Relevance: Information should be relevant to the task at hand and the needs of the user.
Value: Information should be valuable and useful to the receiver.
Accessibility: Information should be easily accessible to authorized users.
Security: Information should be protected from unauthorized access, disclosure, modification, or destruction.

Inaccurate Information

Inaccurate information can lead to costly mistakes for businesses.
The cost of these mistakes can be significant, reaching thousands or even millions of dollars.

Data Characteristics

The importance of specific data characteristics varies depending on the type of data required.

System Definition

A system is a group of interconnected parts that work together to achieve a specific goal.

System Components

Systems are comprised of inputs, processing mechanisms, outputs, and feedback loops.

System Performance Standards

Efficiency measures the ratio of output to input, indicating how effectively resources are utilized.
Effectiveness assesses how well a system achieves its objectives.
System performance standards are specific goals for the system, outlining desired outcomes and levels of achievement.
