Data Modeling with the Unified Star Schema

The Star Schema is a well known practice in Data Modeling. Everyone likes it, because it is easy to query. But how do you query two star schemas at the same time? Is it really so easy? A Business Intelligence environment may have hundreds of Star Schemas. Have you ever thought that they can all fit into one integrated single structure? The Unified Star Schema is a new technique which allows pre-connecting the entire data domain of your organization. The central table is called the “Puppini Bridge”. This architecture opens the doors to a new experience of Self-Service Analytics.
