Abstract:
A method and apparatus for an ETL tool utilizing dimension trees. The method may include identifying various dimensions associated with one or more databases, and creating dimension trees based on these dimensions. The method may further include creating an ETL pyramid having multiple levels, linking the dimension trees to corresponding levels of the ETL pyramid, and creating a table for each level of the ETL pyramid to store a subset of the dimension trees that is linked to a corresponding level of the ETL pyramid.
