MDM matching algorithms benefit from all of the following data characteristics except for which of the following?
A . Distinctiveness across the population of data
B . Low number of common data points
C . High level of comparability of the data elements
D . Structural heterogeneity of data elements
E . High validity of the data

Answer: D

Explanation:

MDM matching algorithms benefit from various data characteristics but do not benefit from "Structural heterogeneity of data elements."

Matching Algorithms: These are used in MDM to identify and link data records that refer to the same

entity across different systems.

Data Characteristics:

Distinctiveness: Helps in accurately matching records.

Common Data Points: Aids in the comparison process.

Comparability: Facilitates effective matching.

Validity: Ensures the data is accurate and reliable.

Structural Heterogeneity: Different structures can complicate the matching process, making it harder

to align data.
