Question

Quizplus · Accepted Answer

Normalization is a process of organizing data in a database to reduce redundancy and improve data integrity. It results in a set of well-structured relations that contain all the data mentioned in system inputs and outputs. Option A is incorrect because normalization is a bottom-up process that starts with decomposing complex relations into simpler ones. Option C is inaccurate, as anomalies are unwanted side effects of poor database design and normalization eliminates them. Option D describes a referential integrity constraint, which ensures that the data in one table or relation depends on data in another table or relation, but not a normalization process.
