Subj:   Re: Dimensional Modeling in Teradata Enviornment
 
From:   Ken Hansen

Teradata is promoted as good for both but got even better with the V2R5 release including multi-value compression on most columns. That enhancement has largely overcome the sparse data issues that still beset others. It could also be argued that the 32bit row header is most economically used in multi-column tables. Partitioning on primary index has expedited data recovery from large tables - talking of hundreds of millions of rows.
