Aggregation Strategy Based on Conversion from Dimension Classes to Dimension Hierarchies

摘要

After analyzing the signification of structure and definition about dimension to aggregating operation, confirms that some dimension classes maybe produce analysis demands which are similar to dimension hierarchies, provides CDCDH method for conversion from dimension classes to dimension hierarchies. Gives definition on dimension class and dimension hierarchy, furthermore, gives definition on visible dimension hierarchy and hide dimension hierarchy. About hide dimension hierarchy which shows dimension class, confirms the condition and steps for conversion to apparent dimension hierarchy. In the meantime, produces the realizing procedure about CDCDH method through a practical instance.
