Successfully Transitioning your Team from Data Warehousing to Big Data

-
You are planning to complement your traditional data warehouse architecture with big data technologies. Now what? Should you upskill your existing data warehouse team? Or do Big Data technologies require a completely different set of skills?

What do we mean by big data technologies anyway? For the purpose of this article, I define big data as any distributed technology that is not a relational database. According to this definition, a distributed relational database (MPP) such as Redshift, Vertica, Teradata etc. is not a big data technology. I know. Other definitions for big data exist, e.g. any data volume that we can’t easily fit on a single server.

Tackling big data projects with a data warehouse mindset?

Your company already has a data warehouse built on traditional data warehouse architecture. Either a Kimball collection of conformed data marts or a Corporate Information Factory built on Inmon. Great! You already have a lot of experience running data projects successfully.

They meet many of the requirements of larger submarines at a fraction of the cost.     For example, the Navy awarded Boeing a $43-million contract to build four Orca Extra Large Unmanned Undersea Vehicles (XLUUVs) last year, described in a release from  USNI News .      Boeing based its winning Orca XLUUV design on its Echo Voyager unmanned diesel-electric submersible. The 51-foot-long submersible is launched from a pier and can operate autonomously while sailing up to 6,500 nautical miles without being connected to a manned mother ship, according to the Navy.   In military spending terms, the versatility of the Orca at the price is “fairly unheard of in military spending,” according to an account in  The National Interest . The nearest equivalent was cited as the Navy’s Littoral Com

Canada regulator seeks information from public on Rogers-Shaw deal

(Reuters) - A Canadian regulator on Tuesday asked for information from the public on telecom company Rogers Communications Inc's planned C$20 billion ($16 billion) purchase of Shaw Communications Inc to check for competition concerns. The deal announced in March to create Canada's second-largest cellular and cable operator has attracted regulatory scrutiny.
