, 2018 Extract-Transform-Load (ETL) processes are used for extracting data, transforming it and loading it into data warehouses (DWs). The dominating ETL tools use graphical user interfaces (GUIs) such that the developer “draws” the ETL flow by connecting steps/transformations with lines. This gives an easy overview, but can also be rather tedious and require

Proceedings of the VLDB Endowment, 2013 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.

A taxonomy of ETL activities [PDF]
Proceedings of the ACM twelfth international workshop on Data warehousing and OLAP, 2009 Extract-Transform-Load (ETL) activities are software modules responsible for populating a data warehouse with operational data, which have undergone a series of transformations on their way to the warehouse. The whole process is very complex and of signifi-cant importance for the design and maintenance of the data ware-house.

Benchmarking ETL Workflows [PDF]
, 2009 Extraction---Transform---Load (ETL) processes comprise complex data workflows, which are responsible for the maintenance of a Data Warehouse. A plethora of ETL tools is currently available constituting a multi-million dollar market. Each ETL tool uses its own technique for the design and implementation of an ETL workflow, making the task of assessing ...
