DB2 Data Warehousing Performance And Tuning Workshop

Course:  DWHWPT
Duration:  4 Days
Level:  II
Course Summary

This presentation and hands-on workshop emphasises how to optimise data warehouse design in both non-partitioned and partitioned environments.

Topics central to this presentation include:

  • Giga- and Tera-byte table considerations
  • Partitioning and parallelism
  • I/O design
  • High performance and BI queries
  • DB/DBM configuration parameters
  • How to exploit the DB2 optimizer
