what is query language in dbms

 In the context of database management systems (DBMS), a query language is a specialized programming language used to interact with a database.

Most DBMS use a query language to provide a way for users and applications to interact with the database, to retrieve, update, and manage the data stored in it.

One of the most common query languages used in DBMS is SQL (Structured Query Language), which is used to manipulate data in relational databases. SQL allows users to perform a wide range of operations, including selecting data from one or more tables, inserting new data, updating existing data, and deleting data from tables.

Other query languages used in DBMS include XQuery and XPath, which are used to interact with XML databases, and SPARQL, which is used to query RDF (Resource Description Framework) data, typically used in semantic web applications.

In summary, a query language in DBMS is a specialized programming language used to interact with a database, allowing users and applications to retrieve, update, and manage data stored in the database.
