4 What is ETL? Extraction, Transformation and Load Moving data from A  B Transform, conform data Most often used in Data Warehouse loads Also used for −Data Synchronisation −Data Replication

5 Traditional ETL Architecture In this traditional scenario, the integration process simply conforms data and loads the database server The database performs aggregations, sorting and other operations … … but has to contend with competing demands for resources from user queries This solution does not scale to very large volumes of data and multiple, complex aggregations Traditional warehouse loading ELT

10 Microsoft ETL through the years SQL Server 2005 −Microsoft listened to years of input −Complete rewrite −Separates control flow and data flow logic −Containers −Looping −Transactions boundaries −Restart Points −Easy to make environment agnostic
