How many times have you woken up in the middle of the night wondering why sales of your new product or service you had launched with such fun fair dwindled? After all you had left no stone unturned to market it. In this digital era where most of the shopping is done on the internet, feedback too is expressed on the internet. Customers today like to read reviews before venturing out to buy anything. From mobile phone to movies, cars to holiday packages, everything has a review about it. A quick search for your product reveals the truth. Among the negative reviews, you find one that is spewing venom at your product and causing ripples in the social media.
The person who posted the view is well known on the social media network for his blunt views. Right or wrong, this person has a lot of followers who read his posts and can pass on the views to their contacts.
As a business you would like to have an idea of what has been written about you in these forums. So you go about collecting data in various formats from everywhere you can. This huge collection of data is referred to as Big Data.
Big Data is a collection on complex, unstructured information from everything that is related to or referring to the organization or its products. It is a collection of information from emails, presentations, websites, social media, TV shows etc. There is no limitation on size above which data collection is referred to as Big Data. In case of one organization few hundreds of terabyte s of data could be considered as Big Data, while in other it will take a few hundreds of petabytes before referring to their data as Big Data. The sheer size of data takes it beyond the capability of commonly used software tools to capture, manage and process the data in reasonable time. Although most relational database management systems have evolved with time to process huge amount of data, processing Big Data with the commonly available tools is still proving to be an unsurmountable task.
