Answer 2

The key icon indicate that the particular field is set as a primary key.

• A primary key is a unique column (or set of columns) in a relational database table that is used to identify each record in the table. The key components of a primary key are: It must have a different value for every data row. It cannot have any empty values.
• To refer back to the table that is the source of the primary key, we can include the primary key fields in other tables. The fields in those other tables are known as foreign keys. A strong candidate for a primary key has the following qualities:
• Each row is identified separately.
• It always has a value; it is never blank or null.
• Its values change infrequently (ideally, never).
