Course Overview
Our boot camp teaches advanced mapping techniques with a primary focus on performance & tuning. It offers a thorough review of session partitioning and push-down optimization in addition to creating mappings from SQL. Slowly Changing Dimensions Mappings for types 1, 2, 3, and 6 are included with innovative techniques.
This boot camp is a must for all new and experienced Informatica PowerCenter developers and administrators. It builds on the four-day Foundation boot camp course (INPC-195) and has many challenging labs to reinforce the knowledge and techniques of attendees.
