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.

Who this course is for:
  • 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.
