Big Data

What is Big Data is all about?

        Big Data  is a term applied to data sets whose size is beyond the ability of commonly used software tools to capture, manage, and process the data within a tolerable elapsed time. Big data sizes are a constantly moving target currently ranging from a few dozen terabytes to many petabytes of data in a single data set.   consists of data sets that grow so large and complex that they become awkward to work with using on-hand database management tools. Difficulties include capture, storage search, sharing, analytic and visualizing. This trend continues because of the benefits of working with larger and larger data sets allowing analysts to "spot business trends, prevent diseases, combat crime. Though a moving target, current limits are on the order of petabytes, exabytes and zettabytes of data. 

By a greater than two-to-one margin, organizations today view big data primarily as a business opportunity rather than an IT challenge and are moving quickly to do something about it, big data is the difficulty working with it using relational databases and desktop statistics/visualization packages, requiring instead "massively parallel software running on tens, hundreds, or even thousands of servers. 


Every day, we create 2.5 quintillion bytes of data — so much that 90% of the data in the world today has been created in the last two years alone. This data comes from everywhere: sensors used to gather climate information, posts to social media sites, digital pictures and videos, purchase transaction records, and cell phone GPS signals to name a few. This data is big data.
