Advanced Oracle PL/SQL (and SQL) for Data Warehousing ETL

Course Code: OWHPSQ
Currency: 10g & 11g
Duration: 4 days (hands-on machine workshop)
Audience: ETL developers, PL/SQL programmers and DW architects.
Prerequisites: Completion of our course Data Warehouse Terms, Concepts & Architecture or equivalent knowledge.
Summary: After reviewing data warehousing and extract, transform and load (ETL) basics, the instructor presents the full range of advanced PL/SQL and SQL features which may be incorporated as part of the DW ETL application solution. Skills related to these features are developed in the delegates through realworld examples, hands-on labs, exercises, etc.
Among the ETL topics explored are:
  • Packages
  • Table functions
  • Collections
  • Multi-table INSERTs
  • External tables
  • MERGE statement
  • Cursor variables
  • OWB vs. program coded ETL
  • Transformation options
  • Change Data Capture (CDC)
Finally, ETL PL/SQL (and SQL) applications performance and best practices are discussed in detail, using Oracle's performance measurement tools.
Objectives: Upon completion of this presentation, the delegates should be able to exploit the advanced features of PL/SQL and SQL when carrying out their data warehousing ETL requirements. And the delegate should be qualified to choose optimal PL/SQL and SQL when faced with competing alternatives.
