Question 7

According to the principle of __________,the more recent the data,the more valuable they are.
A)data uncertainty
B)90/90 data use
C)diminishing data value
D)data in context

Accepted Answer

Question 8

A computer system organizes data into a hierarchy that begins with __________,which are the smallest unit of data a computer can process.
A)bits
B)attributes
C)fields
D)bytes

Accepted Answer

Bits are the smallest unit of data a computer can process, consisting of either a 0 or a 1. Fields and attributes refer to groups of related data, while bytes are made up of 8 bits.

Question 9

Magnetic tape uses __________ file organization,whereas magnetic disks and DVDs use __________ file organization.
A)sequential;direct
B)primary;secondary
C)random;direct
D)random;sequential

Accepted Answer

Magnetic tape uses sequential file organization because the data is stored in a linear sequence, which is read or written in the same order. Whereas magnetic disks and DVDs use direct file organization because they allow random access to any particular file. Therefore, option A is the correct answer.

Question 10

Although vendors may claim that their __________ solution creates "a single version of the truth," this claim is probably not true.
A)master data management
B)RFID
C)data mining
D)client/server

Accepted Answer

While Master Data Management (MDM) solutions aim to create a unified and accurate source of data, there will always be some level of inconsistency due to data inputs and ongoing updates. Therefore, even with an implemented MDM solution, it is unlikely to have one completely "true" version of data. RFID, data mining, and client/server are not relevant to the concept of creating a single version of the truth.

Question 11

According to the principle of __________,data must be integrated,processed,analyzed,and formatted into "actionable information."
A)data uncertainty
B)90/90 data use
C)diminishing data value
D)data in context

Accepted Answer

The principle of data in context emphasizes that data must be integrated, processed, analyzed, and formatted into "actionable information" so that it can be effectively used to inform decisions and actions. The other options, such as data uncertainty, 90/90 data use, and diminishing data value, do not directly relate to this principle.

Question 12

__________ is a structured approach for capturing,storing,processing,integrating,distributing,securing,and archiving data effectively throughout their life cycle.
A)Data mining
B)Data management
C)Metadata
D)Data visualization

Accepted Answer

Data management involves all the activities related to the effective management of data throughout its life cycle, including capturing, storing, processing, integrating, distributing, securing, and archiving data. Data mining, metadata, and data visualization are all aspects or components of data management, but do not encompass the full scope of data management activities.

Question 13

Customer name,invoice number,and order date are examples of __________.
A)attributes
B)bytes
C)sectors
D)primary keys

Accepted Answer

Customer name, invoice number, and order date are all examples of attributes, which are characteristics or properties of an object or entity in a database. Bytes and sectors are units of data storage, and primary keys are unique identifiers for specific records in a table within a database.

Question 14

What is the goal of data management?
A)To store data and documents in multiple locations to insure that they are accessible to everyone on demand.
