Question
Which of the following keys is generally used to represents the relationships between the tables?a.None of the aboveb.Primary keyc.Foreign keyd.Secondary key
Solution
The key that is generally used to represent the relationships between tables is the Foreign key (c).
Here's why:
In a relational database, a foreign key is a field (or collection of fields) in one table, that uniquely identifies a row of another table. In simpler words, the foreign key in one table points to the primary key in another table. This is what creates a link or relationship between the two tables.
So, if you have two tables and you want to show a connection between them, you would use a foreign key.
