a) Database Engine
b) Query Processor
c) Transaction Manager
d) Data Dictionary

Answer: b) Query Processor

9. In a DBMS, what is the purpose of the data dictionary?

a) To store the actual data in the database
b) To define the structure of the database including tables and data types
c) To process and execute queries
