Question 1
Write an SQL query to differentiate between system privileges and object privileges in a Database.

Question 2
You have a table named employees in your Oracle database. Create a user named hr_user and grant SELECT and
INSERT object privileges on the employees table to this user. Provide the SQL commands to achieve this.
Question 3
Create a role named finance_role and grant it the following privileges:
• SELECT privilege on the invoices table

commands to perform these tasks.

Question 4
Consider a scenario where you have a complex SQL query that involves joining multiple tables (orders, customers,
and products).
Write an SQL script to create this query and grant SELECT privilege on the necessary tables to a user named
report_user so that they can execute this query successfully. Explain the steps you took and why each privilege is
needed as comments on your SQL script.

Question 5
Write SQL queries to demonstrate the following:
• Grant the CREATE TABLE system privilege to a user named admin_user.
• Revoke the UPDATE object privilege on the inventory table from a user named inventory_manager.
