Certainly, the validity of big data will be a topic at the O'Reilly Strata + Hadoop World conference, to be held next week in San Jose, California.
In one presentation at the conference, Simon Garland, the chief strategist at database vendor Kx Systems, will talk about how big data is noisy and inconsistent, and cannot be managed well using traditional database analysis systems.
Gartner itself seems to remain bullish about the long-term value of big data systems. In a blog entry for Forbes, research vice president Doug Laney predicted that by 2020, most business functions will be reinvented due to the influence of big data analysis.
Much of the data businesses rely on will come from outside sources, Laney noted. How will weather patterns impact a company's sales for the next week? How will sentiments about a company's products expressed social networks drive sales? Such data, coming from multiple sources and in multiple formats, will indeed be "noisy," Laney wrote. But it will also be valuable.
"Your company's biggest database isn't your transaction, CRM, ERP or other internal database. Rather it's the Web itself and the world of exogenous data now available from syndicated and open data sources," Laney wrote.
