A HyperCube can be visually imagined like a reqular Straight Table in Qlik, with a collection of dimensions and metrics as well as additional attributes.
As it's effectively describing how all data is processed, the qHyperCubeDef object plays a significant role in building visualizations or other components that heavily rely on the Qlik engine for calculation.

A fundamental definition of a HyperCube looks as follows:
