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…
This short post is intended to provide a quick warning regarding in-memory columnar and cpu requirements… with a longer post to follow. When a row is inserted or bulk-loaded into a DBMS, if there are no indexes, the amount of cpu required is very small. The majority of the time is spent committing a transaction…
Teradata stock is falling hard due to guidance here that they may miss revenue targets. Analysts are downgrading the stock… but mostly from Buy to Neutral.

I changed the picture to show you the billboard SAP bought on US101N right across from the O HQ… – Rob Larry Ellison announced a new in-memory capability for Oracle 12c last night. There is little solid information available but taken at face value the new feature is significant… very cool… and fairly capable. In…

My friend and a major contributor to the art of database architecture, Chuck McDevitt, died last week. Five years ago Chuck was diagnosed with an advanced cancer and given six months to live. He fought and endured and worked for most of those five years, teaching us all a little about how we might live…
