What does 'SQL' stand for?

The term 'SQL' stands for Structured Query Language. It is a standardized programming language specifically designed for managing and manipulating relational databases. The word "structured" reflects the way data is organized in relational databases—in structured forms such as tables with rows and columns that can be queried and updated.

SQL is widely used for tasks such as querying data, updating records, and managing database structures, enabling users to perform complex operations with relatively simple statements. Its standardized nature means that while different database systems might have their own specific extensions or variations, the core SQL commands are recognized across various platforms, making it easier for developers to work with different database systems.

The other options, while they might sound plausible, do not accurately reflect the nature of SQL. For instance, "Schematic Query Language" and "Sequential Query Language" do not exist as recognized terms in the context of database management. "Standard Query Language" is misleading because while SQL is indeed a standard, the formal definition emphasizes its 'structured' aspect rather than merely being a 'standard'.
