    ODTUG Volunteer Spotlight: Mike Riley
    Read the article

    The latest ODTUG Volunteer Spotlight focuses on Mike Riley. You probably know Mike as the past president of ODTUG (2009-2012) or ODTUG Kscope Conference Chair (2008, 2013-2014). You might even know he was once trapped in an elevator at Oracle OpenWorld 2008 with then-UKOUG President Debra Lilley for two hours until someone from Oracle Support saw her social media plea for help on OTN’s Oracle Mix and called the hotel to rescue them. You might even know Mike through his work as an Oracle ACE. 

    I was amazed to discover Mike had never been the subject of ODTUG’s Volunteer Spotlight before, pretty surprising for a guy who has been at the heart of ODTUG for years. In fact, Mike has overseen the transformation of ODTUG into one of the largest Oracle user groups in the world and expanded the always-super ODTUG Kaleidoscope Conference into the world-best ODTUG Kscope conference we know today. Kscope has grown so successful that it is known as one of the “big six” conferences to Oracle’s product managers and management. 

    Mike was even the original author of the ODTUG Technical Journal Volunteer Spotlight column (what goes around, comes around).

    Oracle PL/SQL Performance Tuning Tips & Techniques” by Michael Rosenblum and Dr. Paul Dorsey is a book you should read soon. A quote from Oracle’s Bryn Llwellyn in the book’s forward says it all “Every professional PL/SQL programmer should study this book and act upon its teachings.”


    Misha and Paul take the scientific route to performance, providing readers the how and why of effective performance. The first chapter sets the tone, showing how performance is an aggregate typically of nine steps from execution of code on the client side, through middleware, to server, and back again to the client. Learn how PL/SQL works from two of the best, whose shared stories of actual issues underline the importance of performance planning and thinking.

    Kevin McGinley, Red Pill Analytics 
    Close your eyes. OK, maybe not quite yet. Read the next few sentences; then close your eyes. Once your eyes are closed, imagine every IT project you’ve ever been a part of, whether as an employee of the company owning the project or a consultant contributing your valuable skills toward the successful completion of the project. Wrap your mind around each project, considering its flaws and successes, its challenges and hurdles. Go ahead and close your eyes now, and when you open them again, try to recall the singular thread that weaves through all of the projects you can remember.

    William Hodges, The Hackett Group 
    Changing dimensions is a well-known and widely discussed challenge in dimensional data modeling, particularly in the context of data warehousing. Oracle Hyperion Planning and its underlying dimensional database and engine (Essbase) are not immune to it. A relatively new Essbase feature called “varying attributes” is Oracle’s response to this challenge. Varying attributes are a powerful feature, but this paper is concerned with situations whose requirements go beyond their capabilities. 

    StevenF.png Confessions of a Quick and Dirty Programmer
    Steven Feuerstein, Oracle Corporation  
    I often use this column to highlight typical mistakes that I make as I go about implementing the code I need for the PL/SQL Challenge or some other project on which I am working. In this issue, though, I'd like to take a big step back and talk about a whole 'nother kind of “quick and dirty,” the challenges it presents for end users, for application developers, for everyone who writes applications on Oracle Database, and for Oracle Corporation itself. The quick and dirty I am referring to can be summed up in one term: "NoSQL." 

    NoSQL and Big Data for the Oracle Professional
    Iggy Fernandez, NoCOUG 
    In this paper, I will dissect and demystify NoSQL technology. The relational camp derides NoSQL technology because NoSQL technology does not play by the rules of the relational camp. Therefore, the relational camp is ignoring the opportunity to incorporate the innovations of the NoSQL camp into mainstream database management systems. For its part, the NoSQL camp derides the relational model as unable to satisfy the performance, scalability, and availability needs of today. I claim that the NoSQL camp derides the relational model because it does not sufficiently understand it. I will go so far as to claim that the NoSQL camp does not fully understand its own innovations; it believes they are incompatible with the relational model and it therefore does not see the opportunity to strengthen the relational model, a very strong assertion that I will defend as I go along.

    Karen Cannell, TH Technology
    As ODTUG opens a new chapter, commencing next quarter, our Journal will be entirely online and released in a distributed format. We will deliver one feature article and one or more of our regular columns right to odtug.com’s Tech Corner on a monthly basis. You will have the opportunity to give online feedback and comment on each article – and you know how we ODTUGgers like to exchange opinions!

    No worries, some things will stay the same—we will keep our same columns, so you can look forward to your favorites each quarter. We will also have greater opportunity and flexibility to bring you more varied content, to keep pace with the ever-growing family of Oracle development tools.

    Our aim is to bring delivery of the ODTUG Technical Journal in line with today’s social media options. These days our members are consuming more information online, and in shorter formats, such as blogs, podcasts, newsfeeds, and tweets, as opposed to formal whitepapers and other printed media. The times, they are a changin’, and ODTUG is keeping up. Join us!
