select_measures

select_measures.flat_table

Select only the indicated measures from the flat table.

Data in multidimensional systems is obtained from operational
systems and is transformed to adapt it to the new structure.
Frequently, the operations to be performed aim to transform a flat
table into a ROLAP (Relational On-Line Analytical Processing) star
database. The main objective of the package is to allow the definition
of these transformations easily. The implementation of the
multidimensional database obtained can be exported to work with
multidimensional analysis tools on spreadsheets or relational
databases.
