Course Introduction Course Objectives

Mapping Techniques – local variables Using local variables: self and forward references

Mapping Techniques – Pivoting data Using the Normalizer transformation (level of occurs, generated keys, examples) Normalizing flat file outputs Denormalizing with unconnected Lookups Denormalizing with the Aggregator (conditional clause and local variables)

Mapping techniques – self-joins Using a Joiner with the sorted input property

Mapping Techniques – Lookup Transformation Using dynamic caching Pipeline lookups

Lab: Self-join, Dynamic Lookup and Denormalizing Mapping Techniques – Surrogate Keys Using the Sequence generator transformation Using a trigger, GUID or update overrides

Advanced Parameter usage Sharing mapping parameters between sessions

Mapping Templates Slowly changing dimension updates (type 1, 2, 3 and mixed) Lab: dimensional updates Data validation and error trapping Comparing the contents of two tables and extracting differences Building parameter files Lab: parameter files

Performance Tuning Understanding PowerCenter’s architecture Getting baseline numbers Using performance counters Identifying bottlenecks Tuning the target and source components Tuning blocking transformations Tuning Lookup transformations Lab: tuning the mapping Tuning the session, caches and memory Using session partitioning Tuning the workflow Running multiple instances of the same workflow Running a session or a workflow on a grid Lab: session partitioning Using PushDown optimization (optional)
