Solution
The correct answer is To create and manipulate databases
Key Points
SQL is the standard language for interacting with relational databases. It is used for:
Creating databases: You can create databases and define their structure using SQL commands such as CREATE DATABASE and CREATE TABLE.
Manipulating data: SQL allows you to perform operations like inserting, updating, deleting, and querying data using commands such as INSERT, UPDATE, DELETE, and SELECT.
Defining schemas: You can define constraints, relationships, and other properties of the data.
Additional Information
To design user interfaces: SQL does not deal with UI design; it focuses on database management.
To display data on web pages: While SQL can provide data that can be displayed on web pages, it is not responsible for displaying the data itself.
To format printed reports: SQL can extract data for reports, but formatting and printing are typically handled by other tools or programming languages.
