Why each option

This question tests understanding of database normalization to resolve data integrity issues caused by redundant or missing data in relational tables.

ADenormalize the Products table.

Denormalizing the Products table would introduce more redundancy and increase the risk of data anomalies, which would worsen rather than resolve missing data issues.

BDenormalize the OrderDetails table.

Denormalizing the OrderDetails table would replicate data across multiple rows, increasing storage overhead and the potential for inconsistencies, not resolving missing data.

CNormalize the OrderDetails table.

Normalizing the OrderDetails table does not address the root cause of the missing data, which originates in the Products table structure, making this an ineffective solution.

DNormalize the Products table.Correct

Normalizing the Products table eliminates data anomalies by organizing product data into a properly structured form, removing redundancy and ensuring referential integrity. This resolves missing data issues because normalized tables enforce consistent relationships, preventing orphaned or incomplete records. Normalization requires minimal development effort compared to application-level workarounds, as it is a structural database change.
