What is Big Data And Data Science?

“Without big data analytics, companies are blind and deaf, wandering out onto the web like deer on a freeway.”

– Geoffrey Moore, Theorist/Management Consultant/Author

Big Data is present almost everywhere nowadays and it is utmost important to preserve the data that is generated so something should not be missed out. Big Data means a huge amount of data that is difficult to process and store obviously. This data can’t even fit into the memory and traditional data processing application software are not able to deal with it. Big Data refers to structured and unstructured both data that a company or organization generates. This data has the potential to be mined and evaluated to get any type of information that is required. Big Data is coming from heterogeneous sources such as media, business apps, public web, machine log data, sensor data, social media and archives (including scanned documents, statements, insurance forms, and print stream files).

Today, Big Data has intrinsic value but it is of no use if that value is not discovered.

Organizations are marking outlines of their goals and missions according to the wishes of their customers. From that huge amount of data which a company captures and generates, only beneficial information is picked that can be categorized and evaluated later. Here appears the need for data science. Data science is exploratory and useful in getting to know about the Big Data. This field consists of scientific methods, systems and processes to extract knowledge and information from data (either present in structured or unstructured form). Data science involves complex Mathematics, statistics, Machine Learning, algorithms, Internet of Things and data analysis in it.

History of Data Science

Many years back, the earlier records of using data were found to track and control the businesses to get an advantage of innovations, creativity, and to create a financial lead.

In 1962, John W Tukey wrote in ‘Future of Data Analysis’: ‘For a long time I thought I was a statistician, interested in inferences from the particular to the general. But as I have watched mathematical statistics evolve, I have had cause to wonder and doubt… I have come to feel that my central interest is in data analysis… Data analysis and the parts of statistics which adhere to it…’

Later in 1977, he wrote a second paper about ‘Exploratory Data Analysis’. The first workshop related to knowledge discovery and data mining was held in 1989. The term Data science was first seen in an international federation of classification in Japan and the topic was ‘Data science, classification and related methods’ in 1996. Big Data and data science evolved together and worked perfectly with technology developing day by day. John W Tukey’s work was edited by William S.Cleveland who developed statistical methods. He later published a paper named ‘Data Science: An Action Plan for Expanding the Technical Areas of the field of Statistics’. For the first time, Cleveland presented Data Science as an independent discipline naming its six areas as:

  • Multidisciplinary investigations.
  • Models and methods for data.
  • Computing with data.
  • Pedagogy.
  • Tool evaluation.
  • Theory.

Automation Of Big Data

The emergence of Big Data has changed everything. As Big Data is present everywhere, why not to get advantage from it instead of wasting it? Digital landscape and organizational operations have been changed altogether as Big Data evolved. With this new trend, technologies are getting polished day by day. Power of Big Data is finding useful patterns from vast data that have predictive values.

Automated processes
improved it by further helping in the identification of data features. Automation of Big Data has helped many organizations and businesses to improve operational costs and efficiency, self-services module and scalability of technologies(related to Big Data obviously). For the understanding of any amount of Big Data, it would take a few weeks to process and analyze it, although it depends on the technology used as well.

As per Barry Delvin at WhereScape;
‘….With automation, we can move from IT’s old need—or necessity—to control everything to empowering both business and IT people to each do what they do best. Business defines what data is needed and how it should be analyzed iteratively, with IT capturing the business needs and applying quality and production values in flight.’

Why is automation necessary? It provides integrated platform for tools and technologies to run IT related tasks (for example designing, building and operating), amending Big Data infrastructure and to speed up those tough tasks that can’t be automated. In the technology industry, it is a part that is dedicated to ADI (automated data integration). It is a new way of thinking and deploying in the commercial atmosphere and environment. It focuses on ingenuity to get rewards from internal customers.

Yes, it is true that data is of huge size so its size varies from time to time. There would be a different amount of data for different time periods. For this, there should be the categorization of Big Data analytics into such portions or segments that it would be easy to label the data and its separation according to different time portions. The feature of recognition of data also addresses in it. In a predictive analysis of Big Data, time is actually reduced by automation so such a robust language is needed that can make prediction problem identification an easier task. A tailored framework is there which works with diverse specifications of data and data labeling.

With automation, we can move from IT’s old need—or necessity—to control everything to empowering both business and IT people to each do what they do best. Business defines what data is needed and how it should be analyzed iteratively, with IT capturing the business needs and applying quality and production values in flight.
