“Big data is at the foundation of all the megatrends that are happening.” — by “Chris Lynch”
The term “Big Data” encompasses large-volume, complex, vast, growing data sets obtained from various different sources. With the enormous data generated every day, one can able to make different patterns and discover relationships using the data. It can be either structured, unstructured, or semi-structured. It holds tremendous potential for improving our lives by recognize patterns and finds use in many innovations like self-driven cars or customizing, developing, improving medical treatments, and accurate weather predictions.
People — Creators of Big Data
People are generating enormous amounts of data every day through their activities on various social media networking sites like Facebook, Instagram, Twitter, and LinkedIn or online photo sharing sites like Flickr, or Picasa and video sharing websites like YouTube. In addition to this massive amount of information gets generated via Blogs, internet searches, more via text messages, email, and personal documents.
It is an astonishing fact that petabytes of data are generated by Facebook users for daily activity. A petabyte is about a thousand terabytes. The sheer size of unstructured data generated by humans fetches a lot of challenges. The ability to store and process unstructured data has critically grown in recent years with new upcoming technologies and tools that are able to store unstructured data. It may be audio/video files or No-SQL databases.
Since the data generated today consists mainly of unstructured data, the ability to handle such data is a great challenge for Big Data.
