Materialized Views and Caching
Explore materialized views and caching techniques to enhance database performance. Learn the difference between standard and materialized views, how to create and refresh materialized views, and how caching reduces query time by storing precomputed data for faster access. Understand the trade-offs between data freshness and performance for real-world applications.
We'll cover the following...

To retrieve this information, the database must run several complex queries that join multiple large tables (Orders, Order_Details, Products, Categories) and perform calculations.

How can we provide this data instantly without overwhelming our database? This is where materialized views and caching come to the rescue. In this lesson, we will explore these powerful optimization techniques to supercharge our query performance. ...
