5. Multidimensional store modeling

5.1 The need for adapted models

The data to be analyzed must reflect the analysts' vision, i.e. appear in a form that facilitates decision-making. This vision corresponds to structuring data along several axes of analysis, representing various notions such as time, geographical location, product nomenclature, etc. This is known as multidimensional analysis. This is known as multidimensional analysis.

Traditional modelling in the form of relationships is inadequate to effectively support multidimensional analyses. To convince ourselves of this, let's consider the relationship in figure 5 a. We can distinguish two axes along which sales for the year...
