Data governance is an approach to managing information across an entire organization. It involves establishing policies and procedures for data management, as well as implementing tools and technologies to support data governance initiatives.

Question 6

Data ________ refers primarily to problems with the media on which the data are stored.
A) clickstreaming
B) degradation
C) scattering
D) rot

Accepted Answer

The answer of Data ________ refers primarily to problems with...

Question 7

Database systems minimize ________.
A) inconsistency
B) independence
C) integrity
D) security

Accepted Answer

Database systems are designed to minimize inconsistency by ensuring that all copies of data are kept consistent across the system.

Question 8

Database systems maximize ________.
A) inconsistency
B) independence
C) isolation
D) redundancy

Accepted Answer

Database systems maximize independence by separating the physical storage of data from the logical structure of the data. This allows for changes to the physical storage of data without affecting the logical structure of the data, and vice versa.

Question 9

________ is a process that spans all organizational business processes and applications.
A) Big data
B) Data governance
C) Master data
D) Master data management

Accepted Answer

Master data management (MDM) is a process that spans all organizational business processes and applications, aiming to ensure the uniformity, accuracy, stewardship, semantic consistency, and accountability of the enterprise's official shared master data assets.

Question 10

We leave valuable trails of data behind when we use tracking and recording devices called data ________.
A) debris
B) exhaust
C) markers
D) roads

Accepted Answer

The correct term is "data exhaust," which refers to the data generated as a byproduct of people's online activities and the use of various digital devices.

Question 11

Databases ________ redundancy; this means ________.
A) maximize; the same data are stored in multiple locations
B) maximize; various copies of the data do not agree
C) minimize; the same data are stored in multiple locations
D) minimize; various copies of the data do not agree

Accepted Answer

Redundancy means that the same data are stored in multiple locations. Minimizing redundancy means that the same data are stored in only one location.

Question 12

Data from a(n) _____ was used to arrest and prosecute Ross Compton.
A) criminal database
B) license plate reader
C) pacemaker
D) video camera

Accepted Answer

Data from Ross Compton's pacemaker was used by authorities to challenge his account of his actions during a fire at his house, leading to his arrest and prosecution.

Question 13

A connected vehicle is equipped with Internet access and usually with a wireless ________.
A) LAN
B) MAN
C) PAN
D) WAN

Accepted Answer

Connected vehicles typically use a wireless Local Area Network (LAN) for communication within a limited area, such as connecting to nearby devices or infrastructure.

Question 14

Which of the following companies is NOT developing cars and self-driving technology/services?
A) Amazon
B) Apple
C) Google

Question 15

________ are those data that visitors and customers produce when they visit a website and click on hyperlinks.
A) Clickstream data
B) Cookies
C) ERP
D) RFID

Accepted Answer

Clickstream data are the data collected about a user's activity on a website, including which hyperlinks they click on, how they navigate through the site, and other actions taken during their visit.

Accepted Answer

The answer of You recently inherited an Alvin and The...

Question 17

________ are a set of core data that span the enterprise information systems.
A) Data governance
B) Master data
C) Master data management
D) Transaction data

Accepted Answer

Master data refers to the core data that are essential to operations in a specific business or business unit. This data is used across multiple systems, applications, and processes.

Question 18

Databases ________ inconsistency; this means ________.
A) maximize; the same data are stored in multiple locations
B) maximize; various copies of the data do not agree
C) minimize; the same data are stored in multiple locations
D) minimize; various copies of the data do not agree

Accepted Answer

Databases aim to minimize inconsistency, which means ensuring that various copies of the data agree with each other to maintain data integrity and reliability.

Question 19

Databases maximize _________; this means ________.
A) independence; applications cannot access data associated with other applications
B) independence; applications and data are not linked to each other, so all applications are able to access the same data
C) isolation; applications cannot access data associated with other applications
D) isolation; applications and data are not linked to each other, so all applications are able to access the same data

Accepted Answer

Databases aim to maximize independence, meaning that applications and data are separated in such a way that changes to data do not require changes to the applications accessing that data. This allows all applications to access the same data without being directly linked to it, enhancing flexibility and scalability.
