Write the SQL statements that define the relational schema (tables)for this database. Assume that person_id, play_id, birth_year
Sunny_sXe [5.5K]

Answer:

  • SQL statement that defines table for Actor

CREATE TABLE Actor(

person_id integer primary key,

name varchar2(40) not null,

birth_year integer check ((birth_year) <= 2019)

);

  • SQL statement that defines table for Play

CREATE TABLE Play(

play_id integer primary key,

title varchar2(60) not null,

author varchar2(60) not null,

year_written integer check ((year_written) <= 2019)

);

  • SQL statement that defines table for Role

CREATE TABLE Role (

person_id integer,

character_name varchar2(60) not null,

play_id integer,

constraint fk_person foreign key (person_id) references actor(person_id),

constraint fk_play foreign key (play_id) references play(play_id),

primary key (person_id, character_name, play_id)

);

Explanation:

Other information that were not added to the question are as below:

The following database contains information about three tables i.e. actors, plays, and roles they performed.

Actor (person_id, name, birth_year)

Play (play_id, title, author, year_written)

Role (person_id, character_name, play_id)

Where: Actor is a table of actors, their names, and the year they were born. Each actor has a unique person_id, which is a key.

Play is a table of plays, giving the title, author, and year written for each play. Each play has a unique play_id, which is a key.

Role records which actors have performed which roles (characters) in which plays.

Attributes person_id and play_id are foreign keys to Actor and Play respectively.

All three attributes make up the key since it is possible for a single actor to play more than one character in the same play

Further Explanation:

In SQL, in order to define relational schema (Tables) for a database, we use CREATE TABLE statement to create a new table in a database.  The column parameters specify the names of the columns of the table.  The datatype parameter specifies the type of data the column can hold (varchar, integer, date)

Answer:

//check which string is greater

if(strcmp(name1,name2)>0)

//assign name1 to first, if the

    //name1 is greater than name2

    first=name1;

else

    //assign name2 to first, if the

    //name2 is greater than name1

    first=name2;

5)

//compare name1 and name2

    if(strcmp(name1,name2)>0)

   

         //compare name1 and name3

         if(strcmp(name1,name3)>0)

       

             //assign name1 to max, becuase

             //name1 is greater than name2 and name3

             max=name1;

how many usable host addresses are available for each subnet when 4 bits are borrowed from a class C IP address
jonny [76]

Answer:

The answer is "14".

Explanation:

Let the IP address = 196.45.204.0

When it borrowed 4 bits

\therefore\\\\ subnet = 28

IP=  \frac{196.45.204.0}{28}\\\\ 28 \to 11111111.11111111.11111111.11110000

If the borrowed bits are left out then:

The Number of useable host addresses:

= {(2^4) - 2} \\\\ = 16-2\\\\ =14

import java.util.ArrayList; // Needed for ArrayList class /** This program demonstrates how to store BankAccount objects in an A
slega [8]

Answer:

import java.util.ArrayList; // Needed for ArrayList class

/** This program demonstrates how to store BankAccount objects in an ArrayList. */

// Class ArrayListDemo6 is defined

public class ArrayListDemo6 {

// main method that begin program execution

public static void main(String[] args) {

// Create an ArrayList to hold BankAccount objects.

// The arraylist is called list

ArrayList list = new ArrayList();

// Add three BankAccount objects to the ArrayList.

list.add(new bankAccount(100.0)); list.add(new bankAccount(500.0)); list.add(new bankAccount(1500.0)); // Display each item using a for loop

for (int index = 0; index < array.size(); index++)

{ BankAccount account = list.get(index);

System.out.println("Account at index " + index + "\nBalance: " + account.getBalance());

}

}

}

Explanation:

The code is written in Java and more comments has been added to make it more explanatory.

The code snippet is a demonstration on Arraylist.

First Arraylist is imported. Then, ArrayListDemo6 class is defined. Then the main method which begin program execution.

Inside the main method, a new Arraylist is created called list.

Then we add three BankAccount object to the list.

Lastly, we use a for loop to display each added BankAccount object.
