Question: 1 / 400

Which of the following is a functionality of SQL?

To store data in a cloud

To create and update records only

To query databases using standard commands called statements

SQL, or Structured Query Language, is primarily designed for managing and manipulating relational databases. One of its core functionalities is to query databases using standard commands known as statements. These statements allow users to perform various operations on the data stored in the database, including selecting specific records, filtering data, joining different tables, and aggregating information. This capability to interactively retrieve and manage data makes SQL an essential tool for database management.

The other options focus on different aspects of data handling or presentation, such as storing data in the cloud, creating and updating records, or visualizing data in charts, but they do not encapsulate the foundational role of SQL in querying and handling relational database operations. SQL's strength lies in its structured approach to retrieving and manipulating data as per user-defined criteria.
