Intro to DB- Chapter 1

What is a database?

• A collection of unrelated data

• A shared collection of related data used to support the activities of a particular organization

• A collection of unstructured data with no organization

• A collection of structured data with no specific purpose

What is the primary goal of a DBMS?

• To provide a convenient and efficient environment for users to retrieve and store information

• To enforce integrity constraints

• To create and maintain databases

• To control the storage, organization, and retrieval of data

What is the concept of Industry 4.0 focused on?

• Data processing and file management

• Interconnectivity, automation, machine learning, and real-time data

• Manual processes and traditional manufacturing

• Data redundancy and inconsistency

What does IoT stand for?

• Internet of Technology

• Industrial Internet of Things

• Internet of Things

• Internet of Transactions

What is the main difference between IoT and IIoT?

• IoT does not include handling industrial processes, while IIoT does

• IoT is less expensive than IIoT

• IoT has more sensitive and precise sensors than IIoT

• IoT is used in industries, while IIoT is designated for individual customers

What is the purpose of a file management system?

• To enforce integrity constraints

• To control the storage, organization, and retrieval of data

• To provide a convenient and efficient environment for users to retrieve and store information

• To manage the data files in a computer system

What is the disadvantage of a traditional file system?

• Data redundancy

• The problem with security

• Limited data sharing

• Data inconsistency

What is the concept of big data?

• Refers to small sets of structured data that can be compiled, stored, organized, and analyzed

• Refers to large sets of unstructured data that cannot be analyzed

• Refers to large sets of unstructured data that can be compiled, stored, organized, and analyzed

• Refers to large sets of structured data that can be compiled, stored, organized, and analyzed

What is the role of end users in a database system?

• Responsible for defining the content, the structure, the constraints, and functions or transactions against the database

• Implement specific application programs to access the stored data

• Access the database from the terminal end and use the developed applications without knowledge of the database design

• Responsible for authorizing access to the database and monitoring its use

What is the advantage of a database approach over a traditional file system?

• Limited data sharing

• Reduced data redundancy

• Data inconsistency

• Data redundancy
