What role does SQL play in software development?

SQL, or Structured Query Language, is a vital component in software development because it enables database management. It is specifically designed for interacting with relational databases, allowing developers to perform tasks such as querying, updating, inserting, and deleting data efficiently. Through SQL, developers can manipulate and retrieve data stored in a database, enabling applications to interact seamlessly with their underlying data structures.

For instance, when a software application needs to display user information, retrieve transaction records, or update inventory levels, it relies on SQL to communicate with the database and perform these operations. This capability is essential in creating dynamic applications that respond to user interactions and maintain relevant data integrity.

The other roles listed—facilitating web design, ensuring cybersecurity, and improving user interface—are important aspects of software development but do not directly pertain to the specific function of SQL. While SQL can indirectly support certain elements of web design through data retrieval for dynamic content, its primary role is centered around database management, making option C the correct choice.
