With such a question you can write a book and even then you will not cover all the scenarios taking into account that solutions depend on rdbms version.

You can first read:
- OraFAQ Forum Guide, Performance Tuning section
- Performances Tuning sticky
- OraFAQ Performance Tuning
- Rosco's SQL Tuning Guide
- Tuning High-Volume SQL Wiki page

You can also have a look at Database Performance Tuning Guide.

Regards
Michel

Hi michel, thanx for your quick and strong reply.
Since I am new to data warehousing, I haven't come across many.
As you suggested I will read and make use of those in my project.
