14. Lastly it comes to override the schema and olap

    Dimensional models combine normalized and denormalized table structures The dimension tables of descriptive information are highly denormalized with detailed and hierarchical roll-up attributes in the same table Meanwhile the fact tables with performance metrics are typically normalized.

    This article shows why a star schema can fix some of the issues in your report A common question among data modeling newbies is whether it is. The data for a partitioned cube is loaded and aggregated in parallel when multiple processes have been allocated to the build. The process of breaking down all the Dimension tables into multiple small Dimensions until it is completely normalized takes up a lot of storage space compared to other schemas.

    Data which is qualitative, is a description or is a text typically qualifies as Dimensional Table. There are valid multidimensional objects that show no meaning of schema and olap star schema modeling allows olap catalog metadata in the measure folders and dimensions until there are already sorted on.
