Different Stages of the Data Pyramid

              The DIKW pyramid represents the relationships between data, information, knowledge, and wisdom. Each building
              block is a step towards a higher level - first comes data, then is information, next is knowledge, and finally comes
              wisdom. Each step answers different questions about the initial data and adds value to it. Let's learn about them.
                 • Data (Base Level)
                    ✶ In this stage data is in its most basic form, unprocessed and unstructured.
                    ✶ It has no meaning and is not very useful in this form.
                 • Information
                    ✶ It is a processed data that collectively carries a logical meaning.
                    ✶  It is obtained by analysing raw data to make it easier to measure, visualise, and analyse for decision-making.
                    ✶  By asking relevant questions about 'who', 'what', 'when', 'where', etc., we can derive valuable information from
                   the data and make it more useful for us.
                 • Knowledge
                    ✶ It is useful information that leads to a deeper understanding.
                    ✶ It represents a more profound comprehension of how things happen.
                    ✶ It is the ability to use information to achieve desired output.
                 • Wisdom (Top Level)
                    ✶ It represents the highest level of understanding. Wisdom is knowledge applied in action.
                    ✶ It is the ability to understand why things are happening in a particular way.
                    ✶ It involves critical thinking to interpret data and make good consistent decisions.
              Let's understand data pyramid with a simple "Traffic Light" example:





                                                     I need to stop the car
                                                                                            Wisdom


                                  Traffic light in my direction has turned red             Knowledge


                       South facing traffic light on ABC street has turned red
                                                                                           Information

                                                       Red, Traffic_Light_1
                                                                                              Data
              Let us see another example of creating a data pyramid for planning a picnic as a student after receiving the
              official letter from school:




                                                      Decision-making based on a holistic understanding of the picnic
                            Wisdom                    experience and its broader implications.
                                                      Significance of the picnic and its potential impact on social
                           Knowledge
                                                      interaction, relaxation, and personal well-being.

                           Information                Research the picnic location to learn about its amenities, facilities, and
                                                      nearby attractions. Checking the weather forecast for the picnic day.

                             Data                     What to bring, dress code, and expected behaviour.
