Chapter 4. Data modeling: End to end
Modeling touches all elements of a data warehouse implementation, from the
logical model representing the business logic, the dimensional, and the OLAP
models imparting order, to the physical data model simulating a real database.
In this chapter we cover this modelling evolution, starting with our business
questions, and ending with the implementation of an InfoSphere Warehouse
solution. This process touches upon the tools required to develop and mange
these models and the interfaces between them.
It is not the intention within this chapter to dig deep into the details of the tools
utilized within this end-to-end modelling process, but rather to give an overall
example of their role in a model’s journey, and the interfaces between these
tools. There are many excellent IBM Redbooks that cover the individual tools in
depth; these are referenced within the chapter.
The Redbooks publication Dimensional Modeling: In a Business Intelligence
Environment, SG24-7138, is a suggested companion to this chapter.
