TL stands for Extract, Transform, and Load, and is most commonly associated with data ware-
housing; however, many businesses require ETL processes without ever moving into the realm
of the data warehouse. For example, a call center that processes the insurance claims of hun-
dreds of insurance companies must import each client companies’ location and policy data. That
data must live in both systems, and because both systems almost always have different data sche-
mas, you must perform a constant transform process on the data to achieve proper data integrity
and synchronization. Enter the ETL developer armed with SSIS.

Integration Services offers a lot of ETL bang for the buck in the world of Enterprise ETL tools. The
multitude of new features offered in SSIS in SQL Server 2012 addresses many of the reported com-
plaints about the steep learning curve and the diffi culty of using confi gurations.
