The objective of this article is to describe about free Big Data courses available online.
About Big Data:
The business landscape keeps on widening so rapidly that traditional management, business and computing courses are not adequate enough to meet the requirement that will be arising out in near future in the business world. The traditional methods are of repetitive and rule-based in nature which by virtue of its being incapable of coping up with the newly emerging trend will be gradually replaced by Artificial Intelligence. In the knowledge era, the most value added job is going to be to manage knowledge, which includes how knowledge is created, mined, processed, shared and reused in different trades and industries. On the other hand, the amount of data and information getting generated day by day is becoming so huge and exponential that in another three years the size of the digital universe will reach 40 zettabytes from all sources including, websites, weblog, sensors, and social media. Therefore, needless to say, Big data is bound to play a vital role in bringing about a transformation into all spheres as to how we live, work and even think. These trends will have tremendous positive impact on how we look into the changing environment all around the globe and create policies.
In other words, Big data is a term used to represent large volume of data collected for analytical purpose which but for Big Data, can not be handled using the traditional data processing application software, as currently the pace at which the volume of data being generated in all sectors all over the world is too large and rapid to be contained within the traditional system. Big Data which can be characterized by 7Vs viz Volume, Velocity, Variety, Variability, Veracity, Visualisation and Value will, not only be accommodative to fulfil the present and future requirements but will also generate insights and value so that based on which an organisation can make better business decisions that will be useful in forming better business strategy and hence assured continual growth of the organisation.
