What components of a relational DBMS do you know?

The main components of a relational DBMS include:

• Storage Engine — responsible for physical storage and management of data on disk.
• Transaction Manager — ensures atomicity, consistency, isolation, and durability (ACID) of operations.
• Query Optimizer — analyzes SQL queries and constructs the optimal execution plan.
• SQL Query Processor — parses, checks, and executes SQL queries.
• Lock Management System — provides correct concurrent access to data.
• Data Catalog (Metadata) — stores information about the database structure, tables, indexes, and access rights.
• Indexes — data structures to speed up search and retrieval.

These components together ensure efficient storage, processing, and protection of data.
