Querying Postgresql Databases PowerPoint PPT Presentations

The Querying PostgreSQL Databases course from Koenig offers insightful training on intermediate level querying of SQL using PostGreSQL.

One of the leading factors for bad database performance is slow SQL queries. Slow queries directly impact database performance, which also causes many types of application performance issues. As DBAs, it is critical to monitor, find, and rectify slow queries. Addressing SQL query slow performance is one of the top tasks performed as a part of the database optimization process. In this PPT, we will talk about slow queries and how to handle them for some databases.
