Types of Data
- Data comes in different types, such as:
- Text
- Image
- Video
- Numbers
- Spreadsheets
- Sound
- Example of data: "Deepu", 11, science, A
Data vs. Information
- Data is raw, unprocessed, and unorganized, whereas information is processed, organized, and structured to provide context and meaning.
- Information is more useful and relevant than raw data.
DIKW Model
- The DIKW model is a hierarchical framework representing the progression from data to wisdom.
- The model consists of:
- Data: Raw facts, figures, and symbols that have not yet been processed or interpreted.
- Information: Data that has been processed, organized, and structured to provide context and meaning.
- Knowledge: Information that has been assimilated, understood, and applied to make decisions or solve problems.
- Wisdom: The ability to make sound judgments and decisions based on knowledge.
Characteristics of DIKW Model
- Data:
- Unorganized and unprocessed
- Can be quantitative or qualitative
- Examples: sensor readings, transaction records, survey responses
- Information:
- Provides answers to "who", "what", "where", and "when" questions
- Examples: reports, summaries, graphs, and charts derived from raw data
- Knowledge:
- Involves the interpretation of information
- Provides answers to "how" questions
- Often involves personal experience
- Wisdom:
- Involves the synthesis of knowledge with deep understanding
- Provides answers to "why" questions
- Includes ethical, philosophical, and holistic perspectives
Transformation Process
