A taxonomy of ETL activities
2009
Proceeding of the ACM twelfth international workshop on Data warehousing and OLAP - DOLAP '09
Preserved Fulltext
In doing so, we follow a black-box approach and provide a taxonomy that characterizes ETL activities in terms of the relationship of their input to their output and provide a normal form that is based ...
However, each one of them follows a different approach for the modeling of ETL activities; i.e., of the building blocks of an ETL workflow. ...
A RATIONALE FOR THE TAXONOMY An ETL workflow can be seen as a directed graph. The nodes of this graph are activities and recordsets. ...
