Big Data is described as the large volume of data both structured and unstructured. It is a data whose scale, variation and complexity require new techniques, algorithms, and analysis to manage it and extract hidden knowledge and value from it. Big data is a very big data due to the introduction of communication means like social networking, online banking and financial transaction etc. Every year the amount of data produced by people is growing rapidly. The amount of data generated by humankind in the beginning of 2003 was 5 billion gigabytes. The same amount is created in every two days in 2011 and in every ten minutes in 2013 and in every sixty seconds in 2015. At present, the world generates around 2.5 quintillion bytes of data every day. This rate is growing rapidly and all these data generated is meaningful and can be utilized if processed with right tools and techniques.

Big Data vs Data Science | The Big Data Problem | Need of Data Science

Data Science deals with structured and unstructured data. In principle, everything that relates to data cleansing, preparation and analysis lie within the scope of Data Science. Big Data implies huge data volumes that cannot be processed effectively with traditional applications. Big Data processing begins with raw data that is not aggregated and it is often impossible to store such data in the memory of a single computer. Data Science looks to create models that capture the underlying patterns of complex systems and codify those models into working applications. Big Data looks to collect and manage large amounts of varied data to serve large-scale web applications and vast sensor networks.
