What is Big Data?

Every day, we create 2.5 quintillion bytes of data. This data comes from everywhere i.e. from sensors, posts to social media sites, digital pictures and videos, purchase transaction records, and cell phone GPS signals etc. If the data generation is increasing day by day then it will become more complex to store and process these datasets via traditional approaches. The graph shows the growth of digital data compared to :

 

Defining Big Data:

Big data means the huge amount of data which is beyond the processing capability of traditional data management system to manage and analyse the data in a specified time span.Big Data comes from many sources, some of them are digital media,online transaction records, cellphone signals etc.

For example, if you have 10TB(Tera Byte) of image files, upon which some processing needs to be done such as resizing and enhancement of images within the given time frames. If you use the traditional systems to perform this task you would not able to accomplish this task within the given timeframe because the computing resources of the traditional system would not be sufficient to accomplish this task. So, these 10 TB of data is referred to as Big Data.

The main challenge of Big Data is storing and processing the data at a specified time span. To perform this task using traditional conventional methods is not good practice. In order to get rid of this traditional approach to analyse and store the Big data, Hadoop technology is developed.
