Informatica Power Center is an enterprise data integration platform (ETL) used by 5000+ Fortune 500 companies. It extracts data from source systems (SAP, Oracle, Salesforce, databases), transforms it (joins, aggregates, enriches), and loads it into data warehouses (Snowflake, Redshift, Teradata). It's a visual tool: you draw pipelines (source → transformation → target) without writing code. Under the hood, it generates SQL and distributes execution across parallel threads.
