A properly designed ETL system extracts data from source systems and enforces data type and data validity standards and ensures it conforms structurally to the requirements of the output. Some ETL systems can also deliver data in a presentation-ready format so that application developers can build applications and end users can make decisions. [1]
Typically, users hand over the data transformation task to developers who have the necessary coding or technical skills to define the transformations and execute them on the data. [ 8 ] This process leaves the bulk of the work of defining the required transformations to the developer, which often in turn do not have the same domain knowledge as ...
