SAP NetWeaver 7.0 ETL and EII
ETL and EII describe two common ways for accessing data from any source systems. ETL is typically used to consolidate and integrate it in a data warehouse; the source data is physically copied and transformed. EII (often also denoted as federated query) is the real-time approach that access data directly - without a redundant physical data store. This presentation describes both concepts that are based on SAP NetWeaver Business Intelligence (BI) technology.
