Answer:

False          

Database management systems are expected to handle binary, unary and ternary relationships.

Explanation:

Unary Relationship: It is a recursive relationship which includes one entity in a relationship which means that there is a relationship between the instances of the same entity. Primary key and foreign key are both the same here. For example a Person is married to only one Person. In this example there is a one-to-one relationship between the same entity i.e. Person.

Binary Relationships: It is a relationship involving two different entities.   These two entities identified using two relations and another relation to show relationship between two entities and this relation holds primary keys of both entities and its own primary key is the combination of primary keys of the both relations of the two entities. For example Many Students can read a Book and many Books can be obtained by a Student.

Ternary Relationships: is a relationship involving three entities and can have three tables. For example a Supplier can supply a specific Part of many Mobiles. Or many Suppliers may supply several Parts of many Mobile models.

The assignment symbol can be combined with the arithmetic and concatenation operators to provide augmented assignment operations
uranmaximum [27]

Answer:

Yes, we can.

Explanation:

We can combine with the arithmetic and the concatenation operators to provide augmented assignment operations in the programming language Python.

This mean we can abbreviate expressions like n = n + 1

For example:

n += 10 this is equal to n = n + 10

n += "example" this is equal to n = n + "example"

In this example we have

variable = variable operator expression equal to variable operator = expression.

These arguments are often used in Python's loops.

Write a piece of code that constructs a jagged two-dimensional array of integers named jagged with five rows and an increasing n
Ksivusya [100]

Answer:

Explanation:

The following code is written in Java and it uses nested for loops to create the array elements and then the same for loops in order to print out the elements in a pyramid-like format as shown in the question. The output of the code can be seen in the attached image below.

class Brainly {

   public static void main(String[] args) {

       int jagged[][] = new int[5][];

       int element = 1;

       for(int i=0; i<5; i++){

           jagged[i] = new int[i+1]; // creating number of columns based on current value

           for(int x = 0; x < jagged[i].length; x++) {

               jagged[i][x] = element;

               element += 1;

           }

       }

       System.out.println("Jagged Array elements are: ");

       for ( int[] x : jagged) {

           for (int y : x) {

               System.out.print(y + " ");

           }

           System.out.println(' ');

       }

       }

   }
