Which process allows users to interact with databases through graphical controls?

The process that allows users to interact with databases through graphical controls refers to database access methods. These methods provide an interface that enables users to perform database operations without needing to understand the underlying query language or database structure. They facilitate the use of graphical user interfaces (GUIs) to manage data, allowing for actions like adding, deleting, or modifying records through buttons, forms, and menus.

While Data Definition Language is focused on defining the structure of the database, such as creating tables and relationships, it does not provide an interactive graphical interface for users. Data Manipulation Language handles the retrieval and manipulation of data within the database but typically requires knowledge of specific commands rather than a graphical environment. Query processing refers to the execution of queries within a database system, which can involve optimizing and managing the queries but doesn't inherently include user-friendly graphical controls for interaction. Therefore, the correct choice highlights the methods through which users can easily access and manage data visually.
