A Query Language is a specialized programming language used to retrieve and manipulate data from databases or information systems. The most common query language is SQL (Structured Query Language), which is used to interact with relational databases by performing operations like selecting, inserting, updating, and deleting data. Query languages are designed to be intuitive and user-friendly, allowing users to specify what data they need and how it should be processed without requiring detailed knowledge of the underlying data structures. Other examples include GraphQL for querying APIs and XPath for querying XML documents. Query languages are essential tools for efficiently managing and accessing large datasets.
