Question

Chapter 6, Problem 6DQ

Program Plan Intro

Database:

A group of structured data that can be used to serve many applications by centralizing the data and regulating redundant data is called as database.

In the database, data is appeared to users as being stored in only one location.

Database Management Software:

A collection of programs is called as database management system which provides some features such as:

Management of databases

Controlling access to data

Query language to retrieve information

The data in the DBMS (Data Base Management system) is made up of three components such as:

Physical database

Database engine

Database schema

DBMS acts as an interface between application programs and the physical data files.

Database Design:

It is important to design a database because it involves understanding the data relationships, the type of data maintained in the database, data usage, and how the organization need to change to manage data from a company-wide perspective.

The main two aspects of database design are as follows.

Physical design – The actual arrangement of database on direct-access storage devices.

Conceptual design – The abstract model of database from a business perspective.

Question 2 (10 Points): String vs. StringBuilder Create a Question2.java file and finish the following tasks: Task 1. a) Create a 1D array of integers to store 50 integers. b) Store values from 0 to 49 in the array you just created. c) Create a new String Object using no-arg constructor. d) Using for loop to add the array elements one by one to the String (one per loop iteration) Hint: to append an element to a String, use the + operator. e) Output the String on the console. Record and display a run-time it took to append all integers to the String (record run-time of 1.d.)). Please submit a screenshot. The screenshot should match the following example: 012345678910111213141516171819202122232425262728293031323334353637383940414243444546474849 it took 196708 nanoseconds to append 50 integers to the String.| Hint: You can use the following statements to record run-time. long begin, end, time; // we will measure time it took begin = System.nanoTime(); //we measure in nanoseconds. // put…
