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 this post we will consider again the implications of implementing a shared-nothing architecture in the cloud. That is, we will start wondering about how to extend a static shared-nothing cluster deployed into an elastic hardware environment. This is the first of three posts inspired by a series of conversations with the folks at Bityota (Bityota.com). After…
Hi… In between leaving SAP and starting at the Social Security Administration I did some work for Cognilytics and with Intel. They have posted a white paper I composed here, titled “High Performance Commercial Computing in 2015”. Both Cognilytics and Intel allowed me the freedom to build this as I saw fit… so it is not…

The vendor described how they stored photos… I pointed out that photos were clearly not metadata… so they went on to talk about the…
This is the 3rd and final example of a vendor admitting, without admitting, to an architectural limitation. The first two parts on Exadata and Teradata are here and here. Teradata started to get real traction in the EDW space with a shared-nothing architecture in the late 1980’s. At that time the only real competition was…
I composed the video below on a contract for Intel… but they were kind enough to let me tell the story with only a lite promotional touch. I think that you will find the story interesting as it describes 20+ years of systems architecture and suggests where we may well be headed in the next…
This is the second post (see Part 1 here) on how vendors adjust their architecture without admitting that the previous architecture was flawed. This time we’ll consider Teradata and in-memory…. When SAP HANA appeared Teradata went on the warpath with a series of posts and statements that were pointed but oddly miscued (see the references below).…
