Answer:

Option D is the correct answer to the following question.

Explanation:

The following option is correct because three sets type variable i.e., "fruit", "fruit2", "fruit3" has contain the same values in it and then they ask for the option is correct if the all are equal and in the option c, there is the if statement in which check the condition if the variable "fruit" is equal to the variable "fruit2" and the variable "fruit" is equal to the variable "fruit3".

so, that' why the following option is correct.

The option A is not correct because there is no equal function in python and we use the operator == to check the condition.

The option B is incorrect because we can see that there is not equal to (!=) operator.

The option D is incorrect because we can see that there is an or operator are used which means if any of the conditions is true then, they return either the other condition is false.

Referential integrity constraints are concerned with checking INSERT and UPDATE operations that affect the parent child relation

Jet001 [13]

Answer:

a) true

Explanation:

In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.

Basically, there are four (4) types of integrity constraints and these are;

1. Key constraints.

2. Domain constraints.

3. Entity integrity constraints.

4. Referential integrity constraints.

Referential integrity is a property of data which states that each foreign key value must match a primary key value in another relation or the foreign key value must be null.

For instance, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.

Hence, the referential Integrity constraints ensures that the relationship between the data in a table is consistent and valid.

Hence, referential integrity constraints are concerned with checking INSERT and UPDATE operations that affect the parent child relationships.

<em>This ultimately implies that, referential Integrity are rules used in database management systems (DBMS) to ensure relationships between tables when records are changed is VALID (INSERT and UPDATE).</em>

<em>In a nutshell, it always ensures a primary key must have a matching foreign key or it becomes null. </em>

What is wrong with line 1?

Gelneren [198K]

Answer:

The set is a object of the class 'H' and the setY method is a member of G class which is not called by the object of H class.

Explanation:

If a user calls the G function which is not a private by the help of H class objects then it can be called. It is because all the public and protected methods of A class can be accessed by the B class if B extends the A-class.
If any class is extended by the other class then the derived class holds the property of the base class and the public and protected method can be accessed by the help of a derived class object.
The derived class object can be created by the help of base class like written in the "line 1".
But the base class can not call the member of the derived class.
