What does SQL normalization aim to achieve?

SQL normalization aims to reduce redundancy and improve data integrity by organizing data within a database into tables. This process involves structuring the data such that each piece of information is stored in only one place, thereby minimizing duplication. By creating relationships between tables through foreign keys, normalization helps ensure that updates, deletions, and insertions are more manageable and consistent, which directly enhances data integrity.

When data is properly normalized, it decreases the chances of encountering anomalies, such as update, insert, or delete anomalies, where it might be difficult to maintain the accuracy and consistency of the data. Consequently, this process supports better database design by making it easier to enforce database rules and relationships, further solidifying the integrity of the stored data.

The other choices, while they may be outcomes of well-structured databases, do not capture the primary goal of normalization itself. The focus on reducing redundancy and enhancing data integrity is the core principle guiding the normalization process in SQL databases.
