    Top 25+ SQL Tuning Tips for Developers

    Tony Andrews, Themis

    Most relational tuning experts agree that the majority of performance problems with applications that access a relational database are caused by poorly designed programs or improperly coded SQL.  Every programming language has efficiencies and inefficiencies and SQL is no exception.  Does your IT shop or team have SQL standards and/or Best Practices?  This presentation is one that every Db2 developer should see and follow to empower them to become better developers and minimize performance issues.  

     

    BIO:Tony Andrews has more than 25 years’ experience in the development of relational database applications. Most of this time, he has provided development and consulting services to Fortune 500 companies and government agencies. Tony has written literally thousands of queries and programs during his development years and has also served as a database analyst. For the last 10+ years, Tony has been splitting his time between performance and tuning consulting engagements along with training.  His main focus is to teach today’s developers the ways of RDBMS application design, development and SQL programming -- always with a special emphasis on improving performance.  He is a current IBM Champion, and regular speaker at many regional user groups, IDUG NA, and IDUG EMEA.  He is also the author of a book for developers titled ‘DB2 SQL Tuning Tips for z/OS Developers’.

    Advance Query Tuning with IBM Data Studio

    Tony Andrews, Themis

    In my opinion, one of the best query tuning tools on the market.  And if I’m running a project, every developer should have this tool on their desktop.  If you are often curious ‘why’ the optimizer chooses a certain index, join order or  access path then this tool will get you those answers.  And by doing so  helps to get the right solution for query improvement. This presentation is designed for the Db2 professional who desires to understand the fundamental issues with performance for Db2 applications.  Emphasis is placed on understanding optimization, many access paths chosen by the optimizer, filter factors, along with how to read and understand  visual explain access paths. Performance related issues in the areas of database design, indexing, application SQL coding, and data statistics will be addressed.  Presentation has examples in both Db2 z/OS and LUW.
