Lazy ETL in Action: ETL Technology Dates Scientific Data

Provided by: VLD Digital Topic: Data Management Date Added: Aug 2013 Format: PDF
Both scientific data and business data have analytical needs. Analysis takes place after a scientific data warehouse is eagerly filled with all data from external data sources (repositories). This is similar to the initial loading stage of Extract, Transform, and Load (ETL) processes that drive business intelligence. ETL can also help scientific data analysis. However, the initial loading is a time and resource consuming operation. It might not be entirely necessary, e.g. if the user is interested in only a subset of the data.
