Which common database challenge is illustrated by a person receiving multiple copies of an L. L. Bean catalog, each addressed to a slightly different variation of his or her full name?

Answer: data inconsistency

Explanation:

Data inconsistency refers to a condition that happens when similar information is stored in different formats in two different tables, or when is necessary to match data between different tables.

Data inconsistency can result in files having duplicated data, which can likely lead to compromising data integrity. In this example, data inconsistency leads to the same person receiving several L. L. Bean catalog instead of just one.
