Question 78/117

Which of the following are reasons to create and maintain a data dictionary? (Choose two.)

A. To improve data acquisition

B. To remember specifics about data fields

C. To specify user groups for databases

D. To provide continuity through personnel turnover

E. To confine breaches of PHI data

F. To reduce processing power requirements

Correct Answer: B,D

A data dictionary is a collection of metadata that describes the data elements in a database or dataset. It can help improve data acquisition by providing information about the data sources, formats, quality, and usage. It can also help remember specifics about data fields, such as their names, definitions, types, sizes, and relationships. Therefore, options B and D are correct.
Option A is incorrect because it is not a reason to create and maintain a data dictionary, but a benefit of doing so.
Option C is incorrect because specifying user groups for databases is not a function of a data dictionary, but a function of a database management system or a security policy.
Option E is incorrect because confining breaches of PHI data is not a function of a data dictionary, but a function of a data protection or encryption system.
Option F is incorrect because reducing processing power requirements is not a function of a data dictionary, but a function of a data compression or optimization system.
