Final answer:
False. Normalization purity is not always easy to sustain in the modern database environment. Hence, b) is correct.
Step-by-step explanation:
False
Normalization purity is not always easy to sustain in the modern database environment. Normalization is the process of organizing data in a relational database to eliminate redundancy and ensure data integrity.
While normalization helps in maintaining data consistency and reducing anomalies, it can also introduce complexities in terms of performance and efficiency.
In some cases, denormalization techniques are used to improve database performance at the cost of some redundancy. Therefore, it is not always easy to sustain normalization purity in modern databases.
