Question: 1 / 400

Why might a developer prefer using a Structure instead of an Entity in SQL Query outputs?

Because queries become simpler

A developer might prefer using a Structure instead of an Entity in SQL Query outputs primarily due to the ability to simplify queries when dealing with data. Structures can be tailored to hold only specific attributes relevant to the context of the query, without the need to involve the full set of attributes found in the corresponding Entity. This results in a more straightforward and focused output that reflects just what is needed, reducing complexity and making it easier to manage and understand the data returned from the query.

By streamlining the data structure in this way, developers can also better handle specific scenarios where only a subset of data is needed for display, processing, or further operations. Although other options might suggest performance improvements or retrieving fewer attributes, the essential advantage lies in enhancing clarity and targeted data retrieval within the context of the application’s requirements.
