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.

Answer:

Operational excellence

Explanation:

Operational excellence is the execution of a business strategy more consistently and reliably than the competition.

Smooth delivery of services and reliability are key factors that are used to measure operational excellence in businesses.  

<em>The question is simply to test the understanding of the various concepts in business management .</em>

Package delivery and phone companies are businesses that relate directly with the general public, and they have a lot of competition. To thrive, they need operational excellence which covers the effective and consistent satisfaction of their customers.

: Write a function "def countWords(string)" that returns a count of all words in an input string represented by the variable 'st
Zina [86]
We can define a word as a group of characters without a space between them. To find the words of the input string , w can use split(delimiter) which returns a list of strings which had the defined delimiter between them in the input string.

def countWords(string):
words = string.split(" ")
count = len(words)
return count

Here we set the delimiter as the space character, and returned the length of the words list. I split each step into its own line for readability, however the function could be one line:

return len(string.split())

Here, no delimiter is specified. If one isn't given, it will default to split at any whitespace, including space.

2. Write a simple program in C++ to investigate the safety of its enumeration types. Include at least 10 different operations on
erastovalidia [21]

Answer:

Check the explanation

Explanation:

To solve the question above, we will be doing some arithmetic and bit wise operations on enum values. in addition to that, we are asserting the array with INTCOUNT  and also printing the size of array i.e 12 and we are adding BIG_COUNT enum value to 5 and the result is 25.

#include<stdio.h>

enum EnumBits

{

ONE = 1,

TWO = 2,

FOUR = 4,

EIGHT = 8

};

enum Randoms

{

BIG_COUNT = 20,

INTCOUNT = 3

};

int main()

{

// Basic Mathimatical operations

printf("%d\n",(ONE + TWO)); //addition

printf("%d\n",(FOUR - TWO)); //subtraction

printf("%d\n",(TWO * EIGHT)); //multiplication

printf("%d\n",(EIGHT / TWO)); //division

// Some bitwise operations

printf("%d\n",(ONE | TWO)); //bitwise OR

printf("%d\n",(TWO & FOUR)); //bitwise AND

printf("%d\n",(TWO ^ EIGHT)); //bitwise XOR

printf("%d\n",(EIGHT << 1)); //left shift operator

printf("%d\n",(EIGHT >> 1)); //right shift operator

// Initialize an array based upon an enum value

int intArray[INTCOUNT]; // declaring array

// Have a value initialized be initialized to a static value plus

int someVal = 5 + BIG_COUNT; //adding constant and BIG_COUNT variable

printf("%d\n",someVal); //value will be 25

printf("%d",sizeof(intArray)); //value will be 12

return 0;

}
