Which component allows users to interact with different functionalities within a database?

Forms serve as a critical component that enables users to interact with different functionalities within a database. They provide a user-friendly interface that simplifies data entry, navigation, and retrieval. By utilizing forms, users can input data, search for records, update information, and manage data more effectively without needing to directly manipulate the underlying database tables.

The design of forms can be customized, which allows for a tailored experience depending on the needs of the users. This means that forms can have various controls like text boxes, buttons, and dropdown lists to facilitate user interaction. In essence, forms act as a bridge between the user and the database, translating complex database operations into simpler actions that can be performed without specialized knowledge.

The other options, while related to database functionality, do not primarily focus on user interaction in the same way. Reports are used primarily for presenting data in a readable format, queries are designed for extracting specific data based on certain criteria, and modules typically refer to collections of code or procedures that can perform various functions but do not serve as a direct interface for user interaction.
