What does Database Normalization aim to achieve?

Database Normalization is a process primarily focused on organizing the attributes and relations of a database to minimize redundancy and improve data integrity. By structuring a database in such a way that dependencies are properly enforced, normalization helps eliminate duplicate data and ensures that logical data structures are maintained.

This process involves breaking down tables into smaller, related tables and defining relationships between them. As a result, updates to the data can be made in one place, which not only enhances the accuracy of data but also ensures that changes propagate correctly throughout the database. For instance, when a customer's information changes, it needs to be updated in only one location rather than in multiple places, which reduces inconsistencies and errors.

The other options focus on different aspects that are not the primary goals of normalization. Combining databases pertains to data integration rather than organization within a single database. Enhancing visualization relates to how data is presented rather than how it is stored and accessed. Protecting against unauthorized access deals with data security measures rather than the structural organization of the data itself. Therefore, the correct answer reflects the essence and primary purpose of database normalization in achieving efficient data management.
