Joins are how you mix two tables of data.

Consider a pair of tables for people in an apartment building, and pets. Many people don't have pets. A few pets don't have people (the office fish, for example.)

A full outer join will get you all people and all pets, with nulls where there's nothing to line up.

What is PCM system? essay

brilliants [131]

A PCM system consists of a PCM encoder (transmitter) and a PCM decoder (receiver). The essential operations in the PCM transmitter are sampling, quantizing and encoding. All the operations are usually performed in the same circuit called as analog-to digital convert Early electrical communications started to sample signals in order to multiplex samples from multiple telegraphy sources and to convey them over a single telegraph cable. The American inventor Moses G. Farmer conveyed telegraph time-division multiplexing (TDM) as early as 1853. Electrical engineer W. M. Miner, in 1903, used an electro-mechanical commutator for time-division multiplexing multiple telegraph signals; he also applied this technology to telephony.

Marina CMI [18]

Using the knowledge in computational language in C it is possible to write a code that uses a class called "books". Data members of this class are author, title, price, publisher and stock position.

<h3>Writting the code in C++</h3>

#include<iostream.h>

#include<conio.h>

#include<stdio.h>

#include<string.h>

//declaration of class books

class books

{

//data members of books class

public:

char author[20];

char title[20];

char publisher[50];

int price;

int copies;

int stock;

//setData() function to set data of books

void setData()

{

cout<<"\nEnter the following details:\nAuthor's Name:";

gets(author);

cout<<"\nTitle :";

gets(title);

cout<<"\nPublisher :";

gets(publisher);

cout<<"\nPrice :";

cin>>price;

cout<<"\nNumber of copies:";

cin>>copies;

stock=1;

}

//check() function to check if a book is available or not

void check()

{

char t[20],aut[20];

int cop;

cout<<"\nEnter the following details to search for book:\n";

cout<<"\nTitle of the book:";

gets(t);

cout<<"\nEnter Author's Name :";

gets(aut);

cout<<"\nNumber of copies:";

cin>>cop;

if(strcmp(t,title) & strcmp(aut,author) & (cop<=copies))

{

cout<<"\nBook is availabe in store\nPrice = "<<cop*price;

copies-=cop;

}

else

{

cout<<"Not available";

}

};

void main()

{

clrscr();

books bk;

bk.setData();

bk.check();

getch();

}
