Solution

The Storage Manager is the component of the Database Management System (DBMS) that interacts with the file manager of the operating system.

Here's a step-by-step explanation:

  1. The DBMS is composed of several components, each having a specific function. These components include the Evaluation Engine, Execution Planner, Parser, and Storage Manager.

  2. The Evaluation Engine is responsible for executing the query and returning the results.

  3. The Execution Planner is responsible for deciding the most efficient way to execute a query.

  4. The Parser is responsible for translating the SQL queries into a format that the DBMS can understand.

  5. The Storage Manager, on the other hand, is responsible for storing and retrieving data from the database. It interacts with the file manager of the operating system to handle the actual file storage and retrieval.

So, the component of the DBMS that interacts with the file manager of the operating system is the Storage Manager.
