That is all for this tutorial. Thank you for reading to the end. In this tutorial, you got to learn about materialized views in PostgreSQL, and how you can operate on them. Due to their effectiveness, materialized views are extensively used in database warehousing. If you are interested in...
Summary: in this tutorial, you will learn about PostgreSQL materialized views that store the result of a query physically and refresh the data from base tables periodically. Introduction to the PostgreSQL materialized views In PostgreSQL, views are virtual tables that represent data of the underlying...

With AWS DMS, you can create and manage materialized views in Oracle and PostgreSQL databases to improve query performance and enable efficient data access. A materialized view is a database object that stores a pre-computed result set from a query, providing fast access ...
Following exercises cover various aspects of creating and refreshing materialized views in PostgreSQL, demonstrating how to pre-computed data for improved query performance and reporting. 1. Create a Simple Materialized View Write a PostgreSQL query to create a materialized view that selects specific col...
PostgreSQL's built-in materialized views offer the best performance improvement for the least work, but only if stale data is acceptable. Eager materialized views offer the absolute best read performance, but can only guarantee freshness if rows do not go stale due to the passage of time. Lazy...
