because most of the time I'm interested in both groups. On the other hand, there will be a lot of default values if I use one dimension only. I've checked "The Data Warehouse Toolkit", but found no relevant information.
Although dimensions play a vital role in data warehouses, they also play a role in otherapplications. For example, dimensions are used in online analytical processing (OLAP) cubes and in business intelligence (BI) and business analytic (BA) applications. Learn about thedifferences between a data ...
A conformed dimension can be referenced by multiplefact tablesin a data warehouse. The dimension is implemented as either a singledimension tablethat is referenced by multiple fact tables or as multiple dimension tables that are referenced by fact tables in separate data marts within the warehouse. ...
In a data warehouse a degenerate dimension is a key in a fact table that does not have any corresponding dimension table. In adata warehouseadegenerate dimensionis a key in afact tablethat does not have any correspondingdimension table.
In addition, this paper also presents an effective ontology-based tool to automate the modeling process. The tool can automatically generate the data warehouse schema from the ontology of describing the terms and business semantics for the big dimension. In case of any change in the requirements,...
In addition, when we are doing incremental data loads into the data warehouse, we'll need to apply the same rules to the new values to make sure we are only adding truly new customers to the customer dimension. Building a conformed dimension also part of the process in master data ...

In data warehousing, date dimension is the most frequently used dimension. Consequently, when building a cube for a data warehouse in Analysis Services, we almost always have to create a date dimension. In this article I'd like to discuss things that we are likely to come across when creatin...
