Answer: False

Explanation:

This means that the mappings between the two schemas may be specified in either one of these languages.In most relational DBMSs today, there is no specific language that performs the role of SDL. Instead, the internal schema is specified by a combination of functions, parameters, and specifications related to storage. These permit the DBA staff to control indexing choices and mapping of data to storage

Afina-wow [57]

Answer:

The correct answer to the following question will be Option B.

Explanation:

<u>Open System interconnection:</u>

  • A practical and conceptual layout that describes network communication that will be used by the systems that are accessible to interconnection as well as other systems, is called the OSI model. This may also be referred to as the OSI model with seven layers.
  • The OSI model aims to direct developers and creators so that they would modularize with the wireless communication devices and computer programs they build, and to promote a consistent structure that defines the features of a network or telecom system.

Therefore, Option B is the right answer.

Implement the following logic in C++, Use appropriate data types. Data types are represented as either numeric (num) or string.
ICE Princess25 [194]

Answer:

Follows are the modified code in c++ language:

#include<iostream>//header file

#include<string>//header file

using namespace std;

int main()//main method

{

string name,address, MSG_YES, MSG_NO;//defining string variable

int item,quantity,size=6, i=0;//defining integer variable

double price;//defining double variable  

int VALID_ITEM[]={106,108,307,405,457,688};//defining integer array and assign value

double VALID_ITEM_PRICE[]={0.59,0.99,4.50,15.99,17.50,39.00};//defining double array and assign value

bool foundIt=false;//defining bool variable  

MSG_YES="Item available";//use string variable to assign value

MSG_NO = "Item not found"; //use string variable to assign value

cout<<"Input name: ";//print message

cin>>name;//input value in string variable

cout<<"Input Address: ";//print message

cin>>address;//input value in string variable

cout<<"Input Item: "<<endl;//print message

cin>>item;//input value in string variable

cout<<"Input Quantity: "<<endl;//print message

cin>>quantity;//input value in string variable

while(i <size)//defining while that checks i less then size  

{

if (item ==VALID_ITEM[i]) //use if block to match item in double array

{

foundIt = true;//change bool variable value

price = VALID_ITEM_PRICE[i];//hold item price value in price variable  

}

i++;//increment the value of i

}

if (foundIt == true)//use if to check bool variable value equal to true

{

cout<<MSG_YES<<endl;//print value

cout<<"Quantity "<<quantity<<" at "<<"Price "<<price<<"each"<<endl;//print value

cout<<"Total"<<quantity*price;//calculate the total value

}

else//else block

cout<<MSG_NO;//print message  

}

Output:

please find the attached file.

Explanation:

In the above given C++ language modified code, four-string variable " name, address, MSG_YES, and MSG_NO", four integer variable "item, quantity, size, and i", and "integer and double" array is defined, that holds values.

In the string and integer variable "name, address, and item, quantity", we input value from the user-end and use the while loop, which uses the if block to check the "item and quantity" value from the user end and print its respective value.
