I'm an Oracle database developer at Cegal Danmark, specializing in utilizing the SQL and PL/SQL languages to the fullest for efficient data manipulation and analysis. Not just for performance, but also for better maintenance of applications over time, putting SQL wrapped inside a PL/SQL API containing business logic for User Interface to call - this method saves a lot as business logic can be reused when UI often needs change.In general I develop applications with the Oracle database in focus, often integrating the database directly with other apps or webservices, letting the database consume data from other sources or produce data for other targets. For such integration (or sometimes migration) projects I develop pieces of code in practically whatever fits the task best, so I do bits and pieces in C, Java, .NET, PowerShell, scripts, etc.In the analysis field I analyze data directly for reporting using SQL, or I create views for use in analysis tools or extracting data to datawarehouse staging. I can help out with datawarehousing and work with SSIS and biGenius tools, or assist in analysis with tools like Alteryx or BI environments like Targit.I teach SQL and PL/SQL by presenting, blogging, participating in the Oracle community as Oracle ACE Director, and creating weekly quizzes at https://devgym.oracle.com . When other developers learn to use more of SQL than just the basics, I am happy :-) That's also the reason that I wrote the book Practical Oracle SQL (published February 2020 by Apress.)
