The definition of Big Data is simple -- itís the collection of large amounts of information. Going deeper, we include the ability to manipulate this data through analysis. Itís not a storage issue; itís a transaction and analytics issue. If storing massive data were the point, we wouldnít be obsessing about big data. The point is using data from a wide range of sources -- sensor data, demographic info, physical qualities -- to detect patterns and make decisions based on the knowledge derived from those patterns.
The ability to process massive data changes our behavior. Data analysis of stress on new materials allows the automotive and aerospace industries to bring strong, lightweight, sustainable materials into production. Big-data analytics allows plants to become ultra-optimized, greatly reducing energy consumption and reducing the overall cost of manufacturing. Big data is helping sustainable energy sources compete against fossil fuels. Ultimately, big data will keep our cars from bumping into each other.

In a few short years, we will all feel the effect of big data in our cars. They wonít bump into each other as often, and quality problems with deadly accidents and massive recalls will begin to taper off. Google's autonomous car is the icon for big data in automotive. But it will be more. It will include intelligent design, intelligent manufacturing, and intelligent sensors that will reduce accidents dramatically. (Source: thebigdatainsightgroup.com)
Greg no doubt big data is very usefull for HR department as well because we all know these days the functioning of HR has changed completely . It is not just about setting pay roles , increments incentives and so on but the actual function of HR is now employee development , training , making the employee grow , analyzig the skills and positive points and then making strategies and identifying trainings to give. All this requires data , deep understanding of data , analysis and having the potential to work , play and taking out meaningfull results with data .
Greg, I totally agree with you that big data alone is just zero and of no use in order to make big data usefull one should use his or her brains as well. Totally or blindly relying on data will be stupidity one should analyze the data and for analysis brain is required .
The first explanation that I heard of the alleged value of big data was that somehow there would be searches discovering previously unknown relationships between trends. That is an interesting concept that could certainly have potential value. But determining a relationship, or even just an aapparent correlation, between happeningsof any kind and any other kind would certainly require both huge amounys of computational power and huge amounts of relevent data. I see two possible concerns immediately, which the first is "who owns that data?", and the second concern is about privacy of that data. Who has a right to data about what I eat for breakfast on Thursdays? Or how much coffee I drink? And I am certain that a whole lot of more personal data would be somehow tossed into that blob called Big Data. And who would benefit financially from the analysis of all that informnation about me? And who might just be amused to read my statistics?
My point is that a whole lot of the more obvious uses of big data certainly are not going to improve the quality of life for most folks, except for those who need advertising to tell them what they need to purchase and where they need to purchase it.
Really, it looks a whole lot like the future "benefits" from big data will be similar to blasting the lid off of Pandora's Box. And unfortunately for us all, once that happens it will be really hard to put the demons back in the bottle.
Nancy is certainly correct: It is quite an irritation to attempt to locate information on a topic and instantly have 492 sites offering it for sale, whatever it is. And a large portion of the sites don't even have that item actually for sale, they just claimed that they did. So it would be good if there were an added code for seeking to purchase, versus seeking information. And the penalty for claiming to have something for sale and not having it for sale to be a years banishment from the internet. Sometimes it is more like 492,000000 sites claiming to have a product, or at least something with some of the same letters in the name.
I really like the concept of big data is equal to the sum of transaction , interaction and observations . Every telecom firm is using this concept they create an activity, interacts with the customers and then observe what is the reaction of customers. They use CRM systems which comprise of detailed information of every customer and this sytem helps to create BIG DATA
Thanks Rob for such an interesting post no doubt these days Big data is becomming very popular ,Now a days there is not a single multinational which is unaware of big data or which is not equipped with it because today big data is playing a very important role in the success of any organisation.
The slide that caused some concern was the one that showed how big data could bring HR policies in line with actual behavior. While I do agree that statistically there is merit to relying upon big data for desired HR results, over-reliance on big data alone will also cause some bad decisions and eliminate some potentially good candidates. A good balance between big data and common-sense must be found for optimum results in the future.
One problem is Big Data getting it wrong. My son frequently jumps on his friends' computers to purposefully perform searches on subjects that give rather annoying pop-up ads and movie suggestions. Sure, he does it to tease his friends, but it's not uncommon to let someone borrow your computer to do a little work and the next thing you know you're getting ads for a Judy Garland Convention weekend complete with commemorative plates and the entire Andy Hardy, DVD box set ("Hey kids, let's put on a show!").
Major global metropolitan areas are implementing a vast number of technology, energy, transportation, and Internet projects to make the metropolis a friendlier, greener, safer, and more sustainable place to be.
Hereís a look at robots depicted in movies and on TV during the 1950s and 1960s. We tried to collect the classics here, omitting the scores of forgettable B movies such as Santa Claus Conquers the Martians and Dr. Goldfoot and the Bikini Machine. Stay tuned for slideshows of robot stars from later decades.
