PostgreSQL Role and Permission Management
In this lab, you will explore PostgreSQL role and permission management. The primary goal is to learn how to create roles with specific attributes and manage database privileges. You'll grant privileges, switch users, and revoke access.
LabPostgreSQL
PostgreSQL Transaction Management
In this lab, you will explore PostgreSQL transaction management, a crucial aspect of ensuring data integrity. You'll learn to begin and commit transactions, roll back failed transactions, set isolation levels, and simulate locks with concurrent updates. Practice with accounts table and fund transfers.
LabPostgreSQL
PostgreSQL Views Management
In this lab, you will explore PostgreSQL Views Management. The primary goal is to understand and implement different types of views, including simple views and materialized views. You'll learn to define, query, modify, create, populate, and refresh views.
