What does SQL stand for?

SQL stands for Structured Query Language. It is a domain-specific language used in programming and managing relational databases, which allows users to perform various operations such as querying data, updating records, and managing database structures. The term "structured" highlights the way this language is designed to handle structured data, which is data organized into tables where each row is a record and each column represents a field within the record.

Using SQL, users can manipulate and query data efficiently, making it a fundamental tool for database management systems. This versatility is one of the reasons why SQL has become a standard in the industry for operations involving databases.

The other options describe possible languages or concepts, but they do not accurately reflect the established definition of SQL. The term "Simple Query Language" suggests a less complex system that does not encompass the full range of functionalities that SQL provides. "Standard Query Language" might imply a broader application, but it does not accurately align with the historical and formal name of the language. Lastly, "Structured Question Language" diverges from the main concept of data manipulation and querying in databases. Understanding SQL as Structured Query Language is crucial for anyone working with database management and retrieval.
