WORLDCOMP'12 Tutorial: Dr. Saeed Rahimi

Beyond SQL: Oracle Analytic Functions
Dr. Saeed Rahimi
University of St. Thomas, USA

Date: July 17, 2012
Time: 6:00pm
Location: Copper Room


    Relational database management systems and Structured Query Processing (SQL) have been in use for On-line Transaction Processing (OLTP) since early 1980’s. Recently, On-line Analytical Processing (OLAP) applications have become necessary tools for decision makers and business analysts. Although it is possible to use native SQL to perform analytics, this approach is very cumbersome and has many shortcomings. Oracle analytical functions are extensions to standard SQL statements that can be used to answer many Decision Support Systems (DSS) and data warehousing types of questions. By attending this session, attendees will learn how to work with Oracle’s analytical functions such as Cubes, Rollups, Ranking, Top-N, Bottom-N, etc. for real-life type of environments that can be very useful in business analysis. Attendees will have the opportunity to apply what we discuss in this session to answer questions similar to the one that they would face in real life.


    • Participants will have an overview of relational database systems and data warehousing
    • Participants will review the basic SQL statements to solve real life OLTP type of problems
    • Participant will review and learn the advanced SQL statements beyond the standard in performing analytical function in Oracle 11g.
    • Examples of to Oracle’s analytic functions in a hypothetical scenario to drill down, roll-up, slice and dice on a sample database will provide and in-depth understanding of these functions.


    This tutorial will benefit the people in the following (but limited to) job categories:

    • OLAP Developers
    • SQL programmers
    • Development managers
    • Data analysts
    • Data warehouse developers
    • Business intelligence analysts
    • Line managers
    • Scientists
    • Engineers
    • Graduate students studying DSS and OLAP

If you can read this text, it means you are not experiencing the Plone design at its best. Plone makes heavy use of CSS, which means it is accessible to any internet browser, but the design needs a standards-compliant browser to look like we intended it. Just so you know ;)
