Data warehousing, the original driver for ETL technology, isn’t considered as sexy anymore. That’s in part why vendors have used different names to broaden this software category and added new capabilities to keep it relevant.
Informatica is no exception. We’re “the Data Integration Company“, where data integration consists of many different capabilities, only one of which is ETL (granted, the ETL piece is the cornerstone for data warehousing and other data integration projects).
