Datastage Training  

Datastage is a popular ETL tool from IBM. This 50 Hours training will cover all the stages in the tool from an ETL developer perspective. All sessions have hands on sessions with scenario based exercises to help participants mimic the real world setup.

Audience

This is recommended to anyone with basic SQL knowledge who wishes to be an ETL developer.

Datastage Course Highlights:

  • Describe the parallel processing architecture and development and runtime environments
  • Describe the compile process and the runtime job execution process
  • Describe how partitioning and collection works in the parallel framework
  • Describe sorting and buffering in the parallel framework and optimization techniques
  • Describe and work with parallel framework data types
  • Create reusable job components
  • Use loop processing in a Transformer stage
  • Process groups in a Transformer stage
  • Extend the functionality of DataStage by building custom stages and creating new Transformer functions
  • Use Connector stages to read and write from relational tables and handle errors in Connector stages
  • Process XML data in DataStage jobs using the XML stage
  • Design a job that processes a star schema database with Type 1 and Type 2 slowly changing dimensions
  • List job and stage best practices
