Each lesson covers one or more reporting and analysis function / technique in Oracle and uses Oracle 11gR2 for demos. You will get a combination of slideshows and hands-on query exercises, including challenges and brain-teasers to help you think deeper into problems and write simple queries that answer these questions.

All the queries in this course are included for download. Also, make sure you attempt all the challenge exercises before you look at the solutions.

You should take this course if you are looking to up your game in database querying, data mining and business intelligence using SQL queries. A special section is dedicated to Analytic Functions, a really cool set of functions in Oracle that make it easy to write highly scalable, high performance queries with very little code. It starts wit an introduction of Analytic functions and then goes deeper into using these functions to answer business questions. Have fun, as more examples are uploaded to this course.

What are the requirements?

  • Have Oracle installed, preferably Oracle 11gR2 and up.
  • Download Oracle SQL Developer and the JDK and ensure that it runs.
  • You should already be familiar with simple SQL, such as writing basic SELECT statement and GROUP BY functions.

What am I going to get from this course?

  • Use powerful analytic functions for business intelligence in Oracle
  • Use other powerful aggregate functions for business intelligence in Oracle
  • Use manual SQL queries to extract information from a database that answers real-life business questions

What is the target audience?

  • This SQL is meant for anyone who has basic knowledge in writing simple SQL queries and wants to take it to the next level by exploring other robust functions built into Oracle to garner valuable information from an Oracle database that answer real-world business questions.
