I have posted several times about the impact of the Hadoop eco-system on a several companies (here, here, here, for example). The topic cam up in a tweet thread a few weeks back… which prompts this quick note. Fours years ago the street price for a scalable, parallel, enterprise data warehouse platform was $US25K-$US35K per…
There is a new way to think about data warehouse architecture. The Gartner Group calls it a logical data warehouse and it uses database federation to dynamically integrate a universe of data warehouses, operational data stores, and data marts into a single, united, structure. This blog has suggested that there is a special case of the…

In the first two post of this series (here and here) I first suggested that Hadoop could be effectively used as the platform for staging and then suggested that a modern warehouse would have a federation layer that turned it into a logical data warehouse. Figure 3 depicts this extended architecture. But if we have…
In the first post of this series (here) I suggested that Hadoop could be effectively used as the platform for staging. Figure 2 describes the result. In this post I will extend the architecture by adding a data federation feature and turning the entire picture into a logical data warehouse… and then we’ll consider the…
