Oracle SQL Performance Tuning

EDUCBA narrows the SQL study to performance in Oracle. The need for tuning leads into query optimization, indexes and supporting tools. The intermediate course is useful when correctness is established and the next task is explaining or improving execution behavior.

What you will learn

• Identify a reason to investigate SQL performance.
• Compare query and indexing choices.
• Use performance information to evaluate a tuning change.

Who this suits

Learners familiar with relational databases, joins, subqueries, grouping and SQL functions.

Before you enroll

These query foundations are required. Check Oracle access and version compatibility, and compare execution evidence before assuming a rewritten query is faster.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Provider access terms can change; review them before paying.

Put it into practice

Measure a query on a small practice database before and after an index change. Record the plan, output and timing under the same conditions.
