Learn the core concepts of ETL, data integration, and Informatica PowerCenter in a structured course designed to build a strong understanding of how enterprise data is extracted, transformed, loaded, and managed. This course begins with the fundamentals of ETL architecture and the role of Informatica PowerCenter in enterprise data warehousing. You will explore the core components of PowerCenter, including the Domain, Node, Integration Service, and Repository Service, and understand how these components work together within the PowerCenter environment.
You will then learn how data flows from different source systems to target systems. The course covers relational data models, flat file processing, delimited data structures, target system design, data loading principles, Mapping Designer concepts, data types, and metadata integration.
A major part of the course focuses on transformation logic. You will understand the difference between active and passive transformations and learn the concepts behind commonly used transformations such as Expression, Filter, Sorter, and Router. You will also explore advanced transformation strategies using Aggregator, Joiner, Lookup, Sequence Generator, and Normalizer transformations. The course also covers Lookup reference data and cache management, along with Update Strategy concepts for handling insert, update, delete, and reject logic. These topics help you understand how transformation logic can be structured to process and manage data effectively.
