The following tables compare general and technical information for a number of online analytical processing (OLAP) servers. Please see the individual products articles for further information. Please see the individual products articles for further information.
The historical portion of the cubes is also populated from the data warehouse. In this simplified example, the calculations just discussed may be done in the data warehouse for the historical portion of the cubes, but generally, the functional model supports the calculation of other functions, such as ratios and percentages.
