Data, Information, Knowledge and Wisdom
- To learn to read is to light a fire; every syllable that is spelled out is a spark. ― Victor Hugo
Data are values of qualitative or quantitative variables and belong to a set of items.
Data are typically the results of measurements and can be visualised in a vast array of techniques - graphical,image based,characters even by sound or through touch.
Data as an abstract concept can be viewed as the lowest level of abstraction from which information and then knowledge are derived.
Raw data is unprocessed data and refers to a collection of alphanumeric characters representing some measure of something.
The word data is the plural of datum, past participle of the Latin dare, "to give", hence "something given".
In some mathematical domains the terms givens and data are used interchangeably. As a concept in information management data can be numbers, words, images,and are simply referred to as the data.
