Which of the following statements about Multiset tables is correct?

Multiset tables in Teradata are designed to allow for the storage of identical rows, which is a key feature that distinguishes them from Set tables. In a Multiset table, you can have multiple records with the same values across all columns; this means that duplicates are not only permitted but are a fundamental characteristic of how data is stored in these tables.

In contrast, Set tables in Teradata explicitly do not allow duplicate rows, ensuring that each row is unique within the table. This makes the distinction between Set and Multiset tables crucial for data modeling and application logic when considering how to handle duplicate data.

The other statements related to Multiset tables either misrepresent their functionality or are incorrect in context. For example, Multiset tables can indeed store data, including duplicates, making the assertion that they do not store any data incorrect. Understanding these characteristics helps users effectively choose the appropriate table type based on their specific data requirements and the intended application behavior.
