Dimensional Modeling Best Practices
Of course, not all of these data warehouse dimensional modeling tutorial techniques apply to all modeling situations, and your particular use case will dictate which combination of these techniques are required. That is why we recommend a review of your existing system when you are suffering performance issues. It is also the only way to fully exploit the SAP Business Content, the key competitive differentiator of SAP Business Warehouse.
This is a follow-on to our first guide, SAP BW Data Modeling, which introduced you to the subject of InfoCube design. For those of you with some SAP BW Data Modeling background, these may be just a good review.
However, as we took the original information an enhanced it with real world experience, we think you may still learn something from it.
