Which of the following is a benefit of SQL for developers?

The benefit of SQL for developers lies in its capability for efficient data manipulation. SQL (Structured Query Language) is specifically designed for managing and manipulating relational databases. Developers can easily perform operations such as inserting, updating, deleting, and retrieving data using simple and readable syntax. This efficiency allows for more streamlined code and less complex data interactions, which can significantly enhance productivity and effectiveness in application development.

In contrast, while reducing network traffic can be an advantage of well-structured queries and proper database design, it does not directly speak to the broader capabilities of SQL itself. Improving performance on mobile devices is more related to how applications are designed and optimized rather than a unique benefit of SQL. Lastly, stating that SQL increases software maintenance costs is counterproductive, as the clarity and structure provided by SQL can often lead to lower maintenance needs over time, contrary to what this option suggests.
