A foreign key is a column in one table which value must match be the primary key in another table.The forign key provide a linking between the two table.
Suppose we have two table customer and order
customer table:
C_ID Name Age
1 rahul 30
2 sumit 23

C_ID column is the FOREIGN KEY in the Order table
Because the value of C_ID column in order table is matched with PRIMARY KEY table i.e :customer table.So the answer is true .
Modeling is important because it predicts outcomes, involves the knowledge of variables, analyzes the system, incorporates information and avoids biases.
<h3>What is Modeling?</h3>
In computation, modeling refers to the action of taking into account all variables that produce a given outcome and then predict it in a virtual environment.
Modeling is fundamental in system design because enables the prediction of the behavior of diverse variables simultaneously.
In conclusion, Modeling is important because it predicts outcomes, involves the knowledge of variables, analyzes the system, incorporates information and avoids biases.
