              Structured Data
              Structured data is formatted, and has a predefined data type and arrangement. Some examples of structured data that
              we find in everyday life are names, dates, addresses, credit card numbers, stock information, etc. For example,

              We can add, search, modify and manipulate structured data easily. Let’s have a look at the sources of structured data:

              Types of Structured Data
              There are mainly three types of structured data which are:
              •  Date and Time Data Type: As the name suggests, this data type is used to store date and time. There are various
                  formats of storing date and time:


                                                          dd-mm-yyyy                    04-03-2021
