Oracle SQL Performance Tuning

Overview

Class Central Tips

This course is designed to provide you with skills needed to improve query performance in Oracle databases. In real-world scenarios, slow report generation and query execution often result from the sheer volume of data. To address this issue, this course covers topics such as Query Compilation and Execution, Indexing, Materialized Views, Common Table Expressions etc. Emphasis is on practical learning with step-by-step demonstrations. Upon completion, you will master SQL-level performance tuning and eliminating query bottlenecks. Our unique approach showcases query execution before and after applying tuning techniques, ensuring a comprehensive grasp of optimization methods. Course Pre-Requisite: You will need to be familiar with Relational Database Management System (RDBMS) concepts and have proficiency in SQL techniques, including joins, subqueries, set operators, GROUP BY and SQL functions. Target Learner: This course is designed for Database Administrators (DBAs), SQL Developers, Application Developers, Data Analysts seeking to enhance their Oracle SQL Performance Tuning skills. What Will You Learn: By the end of this course, you will be able to: • Compose and optimize indexes for enhanced query performance • Evaluate the utilization of indexes within your queries • Understand the factors influencing Query Compilation • Determine and apply appropriate data types for database columns

Syllabus

Understanding Necessity of SQL Tuning

In this module, you will identify the demography of the tables. Different data types will be explored. Also, select statement execution will be elaborated.

Query Optimization Techniques

In this module, you will understand the different techniques offered by Oracle to know how any select statement gets executed internally. This module also describes the compilation process of any select statement.

Indexing Strategies

In this module, you will interpret how indexes contribute to enhancing the performance of a query, and the hazards of a full table scan are covered.

Performance Tuning Tools and Techniques

In this module, you will understand how hints can be useful to uplift the query execution process. A querying technique known as Inline view is covered. An Oracle object temporary table’s usage for solving real-life problems is depicted.
