Which of the following language categories is MOST commonly used in databases?

Query languages, such as SQL (Structured Query Language), are fundamental to databases as they provide the commands and syntax for tasks like data definition (creating tables), data manipulation (inserting, updating, deleting data), and data retrieval (querying information). They are the primary means of interaction with relational databases.

Assembly language is a low-level programming language specific to computer architecture, not commonly used for direct database interaction.

Markup languages like HTML are used for structuring and presenting content on the web, not for database operations.

Scripting languages are generally used for automating tasks or creating dynamic web content, while they can interact with databases, they are not the primary language category for database operations themselves.
