A data team at Northstar Analytics relies on a database management system to store application data, run SQL queries, and control access. Interviewers ask this question to check whether you understand the system behind SQL, not just query syntax.
What are the key components of a database management system (DBMS)? In your answer, explain:
Keep the answer practical and structured. You do not need to describe every low-level implementation detail, but you should cover the core building blocks clearly: query processing, storage, transaction management, concurrency control, recovery, security, and metadata/catalog management. A strong answer connects these pieces to real database behavior such as reading data, updating rows, handling multiple users, and recovering from failures.
