Data Information , Knowledge and Wisdom.

What is information?


 A systems theorist and professor of organizational change, the content of the human mind can be classified into five categories:

Data

• - information, often in the form of facts or figures obtained from experiments or surveys, used as a basis for making calculations or drawing conclusions
• information, for example, numbers, text, images, and sounds, in a form that is suitable for storage in or processing by a computer

Information

• definite knowledge acquired or supplied about something or somebody
• the collected facts and data about a particular subject
• a telephone service that supplies telephone numbers to the public on request.
• the communication of facts and knowledge
• computer data that has been organized and presented in a systematic fashion to clarify the underlying meaning
• a formal accusation of a crime brought by a prosecutor, as opposed to an indictment brought by a grand jury

Knowledge

• general awareness or possession of information, facts, ideas, truths, or principles
• clear awareness or explicit information, for example, of a situation or fact
• all the information, facts, truths, and principles learned throughout time
• familiarity or understanding gained through experience or study

Wisdom

• the knowledge and experience needed to make sensible decisions and judgments, or the good sense shown by the decisions and judgments made
• accumulated knowledge of life or in a particular sphere of activity that has been gained through experience
• an opinion that almost everyone seems to share or express
• ancient teachings or sayings

 Good and poor information.

 Good information is that which is used and which creates value. Experience and research shows that good information has numerous qualities.

Good information is relevant for its purpose, sufficiently accurate for its purpose, complete enough for the problem, reliable and targeted to the right person.  It is also communicated in time for its purpose, contains the right level of detail and is communicated by an appropriate channel, i.e. one that is understandable to the user. 

Poor information is irrelevant, swamping, unclear, not all threw. Because if you are have all of this in your information you may not make audience understand your information.

Source of information

"Source" means the origin of something. An information source is a source of information for somebody, i.e. anything that might inform a person about something or provide knowledge to somebody. Information sources may be observations, people, speeches, documents, pictures, organizations etc. They may be primary sources, secondary sources, tertiary sources and so on. Empiricism regards sense data as the ultimate information sources, while other epistemologies have different views

	Primary sources Primary sources allow researchers to get as close as possible to original ideas, events and empirical studies as possible. Such sources may include expositions of creative ideas, first hand or contemporary accounts of events, publication of the results of empirical observations or studies, and other items that may form the basis of further research. Examples include:  Novels, plays, poems, works of art, popular culture diaries, narratives, autobiographies, memoirs, speeches Government documents, patents Data sets, technical reports, experimental research results
	Secondary sources Secondary sources analyze, review or restate information in primary resources or other secondary resources. Even sources presenting facts or descriptions about events are secondary unless they are based on direct participation or observation. Moreover, secondary sources often rely on other secondary sources and standard disciplinary methods to reach results, and they provide the principle sources of analysis about primary sources. Examples include:  Biographies Review articles and literature reviews Scholarly articles that don't present new experimental research results Historical studies
	Tertiary sources Tertiary resources provide overviews of topics by synthesizing information gathered from other resources. Tertiary resources often provide data in a convenient form or provide information with context by which to interpret it. Examples include:  Encyclopedias Chronologies Almanacs Textbooks

Information Literacy

 
      The term information literacy, sometimes referred to as information competency, is generally defined as the ability to access, evaluate, organize, and use information from a variety of sources. Being information literate requires knowing how to clearly define a subject or area of investigation;

 
        Information literacy requires an awareness of the way in which information systems work, of the dynamic link between a particular information need and the sources and channels required to satisfy that need (Darch et al. 1997).   


 Information overload 
        Information overload is a description given to the phenomenon where so much information is taken in by the human brain that it becomes nearly impossible to process it. Alvin Toffler, an academic from Russia, is credited with coining the term. Since the term was first used, it has become very popular, especially in the computer age, though some say information overload is more a time and presentation issue, than an actual data issue.

Value of information

     The relative importance of information for decision-making can increase or decrease its value to an organisation. For example, an organisation requires information on a competitor’s performance that is critical to their own decision on whether to invest in new machinery for their factory. The value of this information would be high. Always keep in mind that information should be available on time, within cost constraints and be legally obtained. 

Users of information

       There are many kinds of information users in the modern word, not just personal users. They include users in...

            - Business and industry

            - Education

            - Research and development

            - Entertainment

What is mind map?
     

 A mind map is a diagram used to represent words, ideas, tasks, or other items linked to and arranged around a central key word or idea. Mind maps are used to generate, visualize, structure, and classify ideas, and as an aid to studying and organizing information, solving problems, making decisions, and writing.

The elements of a given mind map are arranged intuitively according to the importance of the concepts, and are classified into groupings, branches, or areas, with the goal of representing semantic or other connections between portions of information. Mind maps may also aid recall of existing memories.
By presenting ideas in a radial, graphical, non-linear manner, mind maps encourage a brainstorming approach to planning and organizational tasks. The mind map can be contrasted with the similar idea of concept mapping. The former is based on radial hierarchies and tree structures denoting relationships with a central governing concept, whereas concept maps are based on connections between concepts in more diverse patterns.
