What does a query in Access allow users to do?

A query in Access is a powerful tool that enables users to retrieve and analyze specific data from a database based on defined criteria or parameters. This means that users can filter and sort data to focus on particular information that meets certain conditions. For example, a user can create a query to display all records of customers who made purchases over a certain dollar amount during a specific time frame. This capability is essential for data analysis, reporting, and making informed decisions based on relevant information.

In contrast to the other options, queries are not primarily designed for storing data securely, directing data entry without validation, or generating random datasets. Instead, they enhance the ability to manage and interpret existing data effectively, which is a core functionality of Access in database management systems.
