SQL (Structured Query Language) SQL (Structured Query Language) is a standardized programming language used for managing relational databases and performing various operations on the data in them.
Yes, SQL is a language. As the SQL acronym pronounces, it is a language. It offers looping, logic directives, variables, and so on. Now, itâs not a language in the same sense as, say, Java or C++: SQL is considered a fourth-generation language (4GL), whereas Java and C++ are third-generation languages (3GLs). Fourth-generation languages are programming languages that are closer to human language than high-level languages like Java. These 4GLs are often used to access databases, such as SQL, where humanlike syntax is used to retrieve and manipulate data. SQL may not be a language on par with Java or C#, but it is a language.
