Explanation:

• A essential key is utilized as a special identifier inside the table to make information parsing more straightforward.
• For each row of data, it must have a unique value.
• It can't have any null values in it.
• Each row must be given a primary key value.
• A data field is a storage location for a specific sort of data that, when combined with other data fields, indicates the location where it is stored.
• A column in a data table that defines the row with which it overlaps is the most common example, although others include class variables in programming languages like Java.
