What does SQL stand for?

SQL stands for Structured Query Language. This terminology reflects its primary function, which is to provide a standardized means of querying and managing data in relational database management systems. Structured Query Language allows users to perform a variety of operations such as retrieving, inserting, updating, and deleting data from databases. The "structured" aspect emphasizes the format in which data is organized in tables, ensuring it adheres to a defined structure or schema, which is essential for maintaining data integrity and reliability.

Other options like "Systematic Query Language," "Simple Query Language," and "Standard Query Language" do not accurately capture the essence of what SQL is designed for and how it operates within the context of data management and database interaction. Thus, structured refers to its function in handling structured data—data that is organized into predefined formats and relationships.
