A developer should favor using a Structure instead of the Entity in the output of a SELECT SQL Query. Do you agree with this statement?

• A. Yes, because queries become easier to maintain.
• B. Yes, because queries will retrieve fewer Attributes and less data.
• C. No, since it is exactly the same.
• D. No, it is preferable to use the Entity instead of the Structure.

Answer: (B)

The statement emphasizes the advantage of using a Structure over an Entity in the output of a SELECT SQL Query. When a developer chooses a Structure, it allows for retrieving only specific attributes that are relevant to the particular use case. This targeted approach means less data is transferred and processed, which can enhance performance and reduce overhead, especially in cases where only a subset of attributes is necessary for the application logic. Using a Structure also contributes to the clarity of the query, as developers can define exactly what data they need, avoiding unnecessary complexity or confusion that might arise from working with an entire Entity that encompasses additional attributes that may not be needed. Additionally, this selective data retrieval can help in optimizing the application’s responsiveness, as less data manipulation is required during the processing of the results.
