Diagram of the standard form implementation of the logical multidimensional model. Cubes consist of measures and dimensions. Dimensions consist of attributes, levels, and hierarchies objects. Cubes are implemented as cubedef objects; measures as measuredef objects; dimensions as dimdef objects; attributes as attrdef objects. Levels are implemented by levellist, member_levelrel, and hier_levels objects. Hierarchies are implemented as hierlist and member_parentrel objects.
