Why are my calculations wrong? (Redux)
I had previously written a very technically focused description of what values you can expect when two calculations intersect in a Voyager workspace. I have since come up with a much less technical explanation comparing Voyager to what you can do with Excel formulas. Dec. 18, 2009

Understanding and configuring memory settings for Voyager's MDAS server
A Voyager deployment contains a mid-tier server called the Multi-Dimensional Analysis Services (MDAS) server. This server is a Java process but also contains a significant C++ part. The fact that the server is a hybrid of Java and C++ has some important consequences for the way memory is used and most importantly has an impact on how much memory should be given to the Java heap. Dec. 11, 2009

Voyager: Understanding scrolling in the crosstab
The Voyager crosstab implements a data loading strategy that balances the need for quick scrolling against query execution time and memory usage when fetching large amounts of data from the OLAP server. Voyager uses the concept of fetching a data window of a certain size within which scrolling is fast. The size of this data window can be configured therefore it is important to understand how Voyager implements scrolling so as to choose the correct size data window for Voyager to operate effectively in a particular scenario. Oct. 9, 2009
