What is Overview of the ETL Process Steps about?
The ETL process loads data from transactional databases into a data warehouse. It involves three main steps - extracting and loading data into staging tables, transforming the data in those tables, and then loading the transformed data into dimension and fact tables. The ETL process is initiated by the DAC client and uses the DAC and Informatica servers to execute mappings and transformations to move the data between the source systems and the data warehouse based on metadata in the Informatica repository.
