Question

what would be a reason why we may want to denormalize our database? a.) we want to eliminate repeating groups. b.) we want to reduce redundancy. c.) we want to increase the number of joins between tables to optimize performance. d.) we may want to prioritize performance rather than data anomalies.

Answer 1

Denormalization can be desirable when performance takes priority over data anomalies. It involves combining multiple tables into a single table to reduce the number of joins required to retrieve data. Therefore the correct answer is d.) we may want to prioritize performance rather than data anomalies.

Step-by-step explanation:

One possible reason why we may want to denormalize our database is d.) we may want to prioritize performance rather than data anomalies. Denormalization involves combining multiple tables into a single table, which can improve performance by reducing the number of joins required to retrieve data. While this can lead to redundancy and data anomalies, in cases where performance is a critical factor, denormalization can be a valid choice. One example is in data warehousing, where denormalization is often used to optimize query performance.
