The extract, transform, and load (ETL) phase of the datawarehouse development life cycle is far and away the mostdifficult, time-consuming, and labor-intensive phase of building adata warehouse. Done right, companies can maximize their use ofdata storage; if not, they can end up wasting millions of dollarsstoring obsolete and rarely used data. Bestselling author RalphKimball, along with Joe Caserta, shows you how a properly designedETL system extracts the data from the source systems, enforces dataquality and consistency standards, conforms the data so thatseparate sources can be used together, and finally delivers thedata in a presentation-ready format.
