What does a SQL query accomplish?

A SQL query is a powerful tool used to interact with relational databases. Its primary purpose is to request data stored within these databases. By using specific syntax, users can define what information they need, from which tables, and under what conditions. For example, a query can retrieve all customer records from a specific city or just the names of products that are available in stock. This querying capability allows for the extraction and manipulation of data, enabling users to perform various operations such as filtering, sorting, and aggregating data to gain insights and make informed decisions.

The other options describe functions that are not related to SQL queries. For instance, formatting documents for printing pertains to word processing software, managing network traffic relates to network management systems, and converting files into different formats involves file conversion tools. Each of these activities falls outside the scope of what SQL is designed to accomplish.
