SQL

This term refers to a specialized domain language designed for interacting with relational databases. It is characterized by a declarative nature, meaning the user specifies what data is needed rather than how to retrieve it, creating a high-level abstraction between the user and the physical storage of data.

As a proper noun representing a specific technical standard, it is treated as an uncountable mass noun. It does not take a plural form; one does not refer to multiple SQLs, but rather to SQL queries, statements, or dialects.
