IBM Cognos TM1 Cube
TM1 cubes exist within the IBM Cognos TM1 solution.
A TM1 cube is a multidimensional database that must contain at least 2 dimensions and 1 fact. The data is loaded into the cube making use of a turbo integrator process. Each cube can be expanded to view all the dimensions that make up the cube. Once a cube is created, it is not possible to add or remove dimensions. You will have to create a complete new cube if you want to remove or add dimensions.
