What is the standard language for relational databases?

The standard language for relational databases is Structured Query Language (SQL). SQL is designed to communicate with and manipulate relational database management systems. It provides a standardized way to perform various operations, including querying data, updating records, inserting new data, and deleting data. SQL is crucial for managing and retrieving data in a structured form, which is essential for data integrity and organization within relational databases.

This language encompasses several sub-languages, such as Data Definition Language (DDL) for defining database structures, Data Manipulation Language (DML) for handling data within those structures, and Data Control Language (DCL) for controlling access to the data. However, SQL as a whole serves as the primary means of interacting with relational databases, making it the correct answer to the question regarding standard language for this type of database.
