Adding a new version to an InfoCube

Add a new version to an Info-Cube

> open the Cube window then click on the Cube name,

> define the desired new versions on an empty column then press OK.


Note that the newly created versions don’t contain data. Use the Align function to feed the new versions.




Automatic creation of cube versions

A optimizer function supports the database designer in the creation of cube versions. When a cube has one version only, a drop-down list to the right of the cube definition window allows to choose from three options Few/Normal/Many. Choosing one of the three options, triggers the optimizer which will automatically generate some aggregated versions. The underlying algorithm evaluates the current cardinality of the entities by which the cube is defined generates aggregates likely to provide performance improvements. The three levels, Few/Normal/Many regulate the number of versions created by the optimizer giving more or less priority to performance versus disk space or RAM utilisation: the option Many produces more versions but will consume more RAM (if in-Memory is used) and more disk space; the lowest level is Few, which creates only a few versions thus saving RAM and disk.



It is possible to run the optimizer also after the first version of the cube has been loaded with data, in this case the versions created by the optimizer must be populated using the Align function.
