add_surrogate_key.dimension_table

Add the surrogate key from a dimension table to the instances table.

internal

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.
