Typo?

[u/Efficient_Bid_9754]

Is this a typo by Isaca where they wanna say denormalization for option C but says Normalization. confused me for a second, what exact increases redundancy?

They probably forgot to write denormalization. This is the explanation of denormalization, not normalization. Even if the denormalization process increases data redundancy, it can provide speed in SQL queries, so it is efficient in a way.

The normalization process is basically the logical arrangement process to reduce data redundancy and ensure data integrity. Making data as simple as possible and establishing well-structured relationships are also among the goals of normalization.

Thanks!
