Published on

Are you a young professional who just got out of college and unsure which career path to follow? Are you thinking about changing your career to something completely new and looking for options? Either way, this webinar is the right one for you. It’s the first in a series that the new ODTUG Career Track Community will bring you to show what Oracle careers look like and where/how to start with them.

During this webinar, we will talk about what an ETL developer career looks like, what the expectations are, challenges, rewards, and which steps are needed to be successful. We will discuss a wide range of topics, such as tools used on the job, certification paths, the importance of social media, user groups, and more. This webinar will be presented by Rodrigo Radtke de Souza, who has been working in the Oracle ETL world for quite some time now and has achieved great accomplishments as an ETL developer, such as Oracle ACE nomination, frequent Kscope speaker, ODTUG Leadership Program participant, and a successful career at Dell.

  4. 4. @RodrigoRadtke @DEVEPM What ETL means? (E)xtract, (T)ransform and (L)oad is the process responsible for pulling data out of source systems, transform it and placing it into a target system. Extract • the data from source systems (Oracle, SAP, ERP, other operational systems, text files, Excel, etc) Transform • cleaning (mapping NULL to 0, "Male" to "M“, "Female" to "F" etc.) • filtering (select only certain values to load) • joining together data from multiple sources (merge) • data validation (if the first 3 columns in a row are empty then reject the row from processing) Load • the data into a data warehouse, data repository for reporting applications, a different/new application, etc.
  5. 5. @RodrigoRadtke @DEVEPM What ETL means? Kimball Group • 34 Subsystems of ETL • Three subsystems focus on extracting data from source systems. • Five subsystems deal with value-added cleaning and conforming, including dimensional structures to monitor quality errors. • Thirteen subsystems deliver data as dimensional structures to the final BI layer, such as a subsystem to implement slowly changing dimension techniques. • Thirteen subsystems help manage the production ETL environment.

  6. 6. @RodrigoRadtke @DEVEPM What ETL means? Where is ETL used? Basically everywhere! • Reporting • Data warehouse/Business Intelligence • Data consolidation • Data replication • Data migration • Big Data/IOT • Cloud
  7. 7. @RodrigoRadtke @DEVEPM Is ETL dead? If there is data, there is ETL. And it is always changing/evolving… Disconnected Mainframes Separate Interconnected Systems Big Data/IOT explosion Manual ETL? Data Warehouse Data Lakes
  8. 8. @RodrigoRadtke @DEVEPM What the job looks like - The good, The bad What is expected from an ETL Developer • Understand data models (Relational, Dimensional) • Analyze business requirements • Develop and unit test mappings • Debug ETL executions • Development estimations • Performance tuning • Integration design Soft Skills • Analytical mindset • Good communication (specially for requirement gathering) • Easiness to work with multiple technologies • “Out of the box” thinking • Team player
  9. 9. @RodrigoRadtke @DEVEPM What the job looks like - The good, The bad Is it good to be an ETL Developer?
