History[ edit ] Danny P. Wallace, a professor of library and information scienceexplained that the origin of the DIKW pyramid is uncertain:
Depending on the context the meanings and use of these words differ.
Both data and information are types of knowledge or something used to attain knowledge. Though used interchangeably, there are many differences between the meanings of these two words.
Data refers to the lowest abstract or a raw input which when processed or arranged makes meaningful output. It is the group or chunks which represent quantitative and qualitative attributes pertaining to variables. Information is usually the processed outcome of data.
More specifically speaking, it is derived from data. Information is a concept and can be used in many domains. Information can be a mental stimulus, perception, representation, knowledgeor even an instruction. The examples of data can be facts, analysis, or statistics.
In computer terms, symbols, characters, images, or numbers are data. These are the inputs for the system to give a meaningful interpretation. In other words, data in a meaningful form is information. Information can be explained as any kind of understanding or knowledge that can be exchanged with people.
It can be about facts, things, concepts, or anything relevant to the topic concerned. The word information was derived from Latin. It also means giving form to an idea or fact.
Data is the plural of the Latin word datum. In the realms of mathematics and geometry, the terms data and given are very often used interchangeably. This is how the term was derived for use in computer realm. If data is at the lowest level in the series, information is placed at the next step.
As an example, if you have a list on the Seven Wonders of the World, that is a data; if you have a book giving details about each wonder, it is information.
Data can be in the form of numbers, characters, symbols, or even pictures. A collection of these data which conveys some meaningful idea is information.
It may provide answers to questions like who, which, when, why, what, and how. The raw input is data and it has no significance when it exists in that form. When data is collated or organized into something meaningful, it gains significance.
This meaningful organization is information.Information: For data to become information, it must be contextualized, categorized, calculated and condensed (Davenport & Prusak ).
Information thus paints a bigger picture; it is data with relevance and purpose (Bali et al ). Data vs Information The frequency of the use of the words data and information are very high in our daily lives. Depending on the context the meanings and use of these words differ.
Both data and information are types of knowledge or something used to attain knowledge. Though used interchangeably, there are many. The DIKW pyramid, also known variously as the DIKW hierarchy, wisdom hierarchy, knowledge hierarchy, information hierarchy, and the data pyramid, refers loosely to a class of models for representing purported structural and/or functional relationships between data, information, knowledge, and wisdom.
"Typically information is defined in terms. Data doesn’t interpret anything as it is a meaningless entity, while information is meaningful and relevant as well. Data and Information are different common terms which we frequently use, although there is a general interchangeability between these terms.
Data is processed by computers, the resulting information can then be used to form judgements and make predictions. data definition: 1. information, especially facts or numbers, collected to be examined and considered and used to help decision-making, or information in an electronic form that can be stored and used by a computer: 2.
information collected for use: 3. information, especially facts or numbers. Learn more.
