In this chapter we have discussed all of the background information pertaining to Cognos TM1 dimensions and cubes that you need to know to prepare for the current IBM Cognos TM1 Developer (Test COG-310) certification exam.
Here are some key points discussed in this chapter:
There are two ways to create cubes—by selecting dimensions from the list of existing dimensions in the Creating Cube window and by using TurboIntegrator to identify and map dimensions and data from an external data source to a new or existing cube.
Each and every TM1 cube must have at least two dimensions and a maximum of 256 dimensions.
Data is loaded into cube cells. A cell is identified by the intersection of dimensions.
When you create a dimension, you identify the leaf-level elements that make up the dimension and, optionally, any hierarchies (consolidations) of the elements within the dimension.
Dimension names can have a maximum of 256 characters.
The four ways to create dimensions are by using...
