Data Warehouse & ETL Tutorial:
Data Warehouse is where data from different source systems are integrated, processed and stored. Data Warehouse data is a non-production data which is mainly used for analyzing and reporting purposes. Business users and higher management authorities use the data warehouse data to analyze, and to make important business decisions. Data Warehouse collects large volume of data from variant sources with many different data formats. The ETL(Extraction, Transformation and Loading) process handles these data and transforms it into a more consistent, standard formatted data. This ETL process is done with the help of an ETL tool and most widely used tools are Informatica, Data Stage, Ab Inito, Oracle Warehouse Builder etc.
