Multidimensional OLAP Server for Linux as Open Source Software

Jedox will release a free open source Linux MOLAP server by the end of the year. A pre-release of the software is expected by mid of 2005.

All data is stored entirely in memory. Data can not only be read from but also written back to the cubes. Like in a spreadsheet, all calculations and consolidations are carried out within milliseconds in the server memory while they are written back to the cube.

I sure hope that by “memory” they include “external” memory because otherwise, their cubes are going to have to be quite small. Normally, you’d at least memory map large files as Lemur OLAP does.
