State of Data #74


#analysisWhat’s wrong with BBC’s ‘Bowel Cancer Map’?

‘Adding up the populations for each area, calculated from the deaths and death rates, I get a UKpopulation of 89.75 million.  Since the true figure for 2008 was about 61 million, that’s rather surprising. ‘


#architectureMongoGate – or let’s have a serious NoSQL discussion” based on the original rant/expose (depending on your POV).

Instead of using the relation model, what the NoSQL movement brings to the table is you can now choose from other ways to reach your own hell. You are free to pick KV-stores, Document DBs or other more complex ways of expressing yourself (beneath some SQL-stuff of course).But does this really transcend the current state of the art? Is this really different from SQL-based systems?!”

#big_data‘Big Data’ is essentially about solving performance problems

#Data_ScienceCloser look at Oracle Big Data Appliance


#DBMSCould you use only SQL to ‘find a secret message hidden in a seemingly random collection of words’ (PDF)? How an Australian, a Dutch and a Russian engineer independently solved it.
 

#idea Is ‘Big Data’ plain evil or just another bubble?

“This is a common characteristic of technology that its champions do not like to talk about, but it is why we have so many bubbles in this industry. Technologists build or discover something great, like railroads or radio or the Internet. The change is so important, often world-changing, that it is hard to value, so people overshoot toward the infinite. When it turns out to be merely huge, there is a crash – in railroad bonds, or RCA stock, or Pets.com. Perhaps Big Data is next, on its way to changing the world.”
