QUESTIONS WITH VERIFIED SOLUTIONS
◉ Wisdom in DIKW.
Answer: Provides a social setting to knowledge; an understanding of
the "why". Can only come by having both knowledge and experience.
◉ Information Systems.
Answer: A collection of data and information used to support the
management of an organization. Also refers to the technical
components and human resources that enable the assembly, storage,
and processing of data and the delivery of information. This has
existed for a lot longer than computers.
◉ Characteristics of Quality Data.
Answer: Relevance - the data being used must apply directly to the
decision being made
Timely - data must be efficient and must be provided in a timely
manner
Thorough - the data must be complete
,Accurate - data should be captured only once, where possible and
should be captured as close to the point of activity as possible.
Reliable - data should reflect stable and consistent data collection
processes across collections points and over time
