Question 8

A ________ is a collection of forms, reports, queries, and programs that serves as an intermediary between users and database data.
A)database application
B)database design
C)data field
D)data model

Accepted Answer

A database application, also known as a database management system (DBMS), includes various components such as forms, reports, queries, and programs that allow users to interact with the database and its data. It serves as an intermediary between the users and the data stored in the database, providing users with a convenient and efficient way to access, manipulate, and analyze the data. A database design refers to the process of creating a blueprint or plan for organizing and structuring the data in a database, while a data field refers to the smallest unit of information in a database. A data model is a conceptual representation of the data, including its attributes, relationships, and constraints.

Question 9

SQL is an international standard language for processing a database.

Accepted Answer

SQL stands for Structured Query Language and is used worldwide as the standard language for managing and manipulating data in a database.

Question 10

The modification or deletion of data in a database is an example of ________ operations of a database management system.
A)statistical
B)analytical
C)administrative
D)processing

Question 11

A(n)________ is a program used to create, process, and administer a database.
A)operating system
B)database management system
C)information system
D)database system

Accepted Answer

A database management system (DBMS) is specifically designed to create, process, and manage databases. While an operating system provides a platform for running software applications, it does not have the same level of functionality as a DBMS. An information system is a broader term that encompasses many different types of software and hardware used to manage information within an organization, and a database system is not a commonly used term in the technology industry.

Question 12

Which of the following is an example of a database management system?
A)MS Excel
B)BigData
C)NoSQL
D)Access

Accepted Answer

Access is a database management system that allows users to store, organize, and manage large amounts of data. MS Excel is a spreadsheet software and not primarily designed for database management. BigData and NoSQL are not database management systems but rather technologies used to handle and process big data.

Question 13

One of the functions of a DBMS is to provide tools to assist in the administration of a database.

Accepted Answer

A DBMS provides various tools and utilities for database administration such as backup and recovery, security management, performance optimization, and data analysis. These tools help in managing the database efficiently and ensure its smooth functioning.

Question 14

The answer of Explain how a database management system processes...

Question 15

Which of the following database administration tasks is related to adaptation?
A)monitoring backup procedures
B)conducting training for users
C)monitoring database performance
D)managing configuration changes in systems

Accepted Answer

Managing configuration changes in systems involves adapting to changes in the database system and ensuring that the changes are properly implemented and tested. This task requires careful planning and adaptation to avoid disruptions to the database system. The other tasks listed (monitoring backup procedures, conducting training for users, monitoring database performance) do not specifically involve adaptation.

Question 16

Which of the following is an international standard language for processing a database?
A)Cassandra
B)DB2
C)SQL
D)MS Access

Accepted Answer

SQL (Structured Query Language) is an international standard language for managing and processing databases. It allows users to interact with the database to create, update, and retrieve data. Cassandra, DB2, and MS Access are also database management systems but are not considered an international standard language like SQL.

Question 17

Which of the following is true of MySQL?
A)It is a Microsoft product.
B)It is license-free for most applications.
C)It is a paid and proprietary database product.
D)It uses Static Query Language (SQL)to manage a database.

Accepted Answer

MySQL is license-free for most applications, although commercial use may require a paid license. It is not a Microsoft product and is not proprietary. MySQL uses Structured Query Language (SQL) to manage databases, not Static Query Language.

Question 18

Owen, the database administrator for a shipping company, is responsible for checking the data model, which is to be used in the database management system, for accuracy and completeness. This is an example of Owen's ________ tasks.
A)development
B)adaptation
C)backup and recovery
D)operation

Accepted Answer

Checking the accuracy and completeness of a data model is a development task, which involves designing and creating a database to meet specific requirements. It is not an adaptation task, which involves changing and modifying an existing database, nor a backup and recovery task, which involves ensuring that data can be restored in the event of a system failure. It is not an operation task, which involves managing the day-to-day functioning of the database management system.

Question 19

A DBMS and database are synonymous terms that can be used interchangeably.

Accepted Answer

A DBMS or Database Management System is a software application that enables users to create, store, manage, update, and retrieve data from a database. A database, on the other hand, is an organized collection of data that is stored and managed by a DBMS. While they are closely related, they are not exactly the same thing and cannot be used interchangeably.

Samuel is the database administrator for Zimline Constructions. He determines the processing rights of employees based on their designation. Team leaders are given greater access to the database than their team members. This procedure of giving selective access is part of Samuel's ________ task.
A)development
B)recovery
C)adaptation
D)operation

Accepted Answer

Giving selective access to the database is part of the regular operation tasks of a database administrator like Samuel. Operation tasks involve carrying out the day-to-day activities necessary to ensure the database is running smoothly and efficiently. Development tasks involve creating new databases, applications or functionalities, adaptation tasks involve adapting the database to meet changing requirements, and recovery tasks involve restoring data after a disaster or failure.
