Which of the following describes something in a database that refers to the unique identifier in the parent table?
In database terminology, a 'foreign key' refers to a field (or collection of fields) in one table that uniquely identifies a row of another table or the same table. The foreign key is defined in the child table, and it refers to the primary key in the parent table. This ensures referential integrity between the two tables. Hence, the correct answer is 'foreign key'.
it should be foreign key
Correct its C. FOREIGN KEY: Unique identifier for a row/record in another database table
A FOREIGN KEY is a field (or collection of fields) in one table, that refers to the PRIMARY KEY in another table. The table with the foreign key is called the child table, and the table with the primary key is called the referenced or parent table.So it's an attribute niggas
The only one
It should be Foreign Key
A.Attribute
A.Attribute
Foreign Key is definitely wrong if the column(field) concerned is in the parent table. The answer should then be the primary key. If primary key is not one of the options then attribute may be right
AFAIK that's the definition of foreign keys
If the real answer is Foreign key and in this exam is Attributes, then what matters is Attribute since if you answer Foreign key in test then you are wrong
Foreign key
C is the only write answer
Foreign keys do not have to be unique. It cannot be the answer imo.
C is correct
A) Attributes
C is the correct answer
The real solution to this question was Attribute and NOT Foreign Key? Why is that?
