Note:The column definitions must match those defined on theOutputtab in the DRS lookup stage. The hash file name must match the name specified in theInputsandOutputstabs. The hash file will provide erroneous values if the column definitions and hash file names are ...
Multidimensionel dataanalyse er også mulig, hvis der anvendes en relationel database. Derved ville det kræve at forespørge data fra flere tabeller. Tværtimod har MOLAP alle mulige kombinationer af data, der allerede er lagret i et multidimensionelt array. MOLAP kan få direkte ...
In this work, we present a new compression method, called BTC, for multidimensional data warehouses. Several methods have been proposed in the literature that can compress the data such as the Bitmap method. The main purpose of BTC is to improve the access time on data. This technique is ...
Image: Dimensional Model Example The following graphic provides an example of a star schema and its primary and foreign key relationships: Although data loaded into the MDW is primarily derived from the OWS, there are exceptions to this rule.
