Cubulus is an analytic engine and a slice and dice Web interface on top of a relational database (MySQL, PostgreSQL, SQLite, and MonetDB at the moment). It caches calculated cells and is able to parse basic MDX queries, with a maximum of two dimensions cross-join on rows and/or on columns. It includes hierarchical charts: the vertical boxes represent hierarchy "on rows", and horizontal boxes represent data sets "on columns" scaled to the "on rows" measure.
