Chapter 8. Data models and DW 2.0 > The scope of integration

The scope of integration

The first step in the building of the data model is the definition of the scope of integration. The scope of integration is the statement of what is to be in the data model and what is not to be in it. The scope of integration is necessary because without it the data model can go on endlessly. It can be extended to include the universe. And when the data model includes the universe, the model is never finished.

Figure 8.3 shows that the definition of the scope of integration is the starting point for the data model.
