摘要：The software processes that facilitate the original loading and the periodic refreshment of the data warehousecontents are commonly known as Extraction-Transformation-Loading (ETL) processes. The intention ofthis survey is to present the research work in the field of ETL technology in a structured way. To this end,we organize the coverage of the field as follows: (a) first, we cover the conceptual and logical modeling ofETL processes, along with some design methods (b) we visit each stage of the E-T-L triplet, and examineproblems that fall within each of these stages (c) we discuss problems that pertain to the entirety of an ETLprocess, and (d) we review some research prototypes of academic origin.
