Storing Planning Data in IBM Cognos: D-Cube (Part 1)

In this two-part article by Ned Riaz, Jason Edwards, and Rich Babaran, we will discuss how data is stored in IBM Cognos Planning Analyst. We will begin by defining the D-Cube and explaining the things that you need to think about before creating the D-Cube. We will discuss the importance of the order of dimensions in enforcing calculation and format priorities. We will show you how you can view the multiple slices of the cube and how you can save a selection of the cube as a separate object. We will explain how you can restructure the dimensions of the cube by adding, deleting, substituting, and reordering dimensions. We will cover some of the important functions available with the D-Cube, including global formatting, exporting, and other options that can make it easier for you to work with the program. We will illustrate how you can use data entry commands that will enable you to enter data, execute mathematical operations, or set restrictions for a cell, a range of cells, or the entire cube. Finally, we will cover Breakback—a powerful feature that allows you to cascade changes throughout the cube simply by making the change to a calculated item.
