THE RELATIONSHIP BETWEEN BIG DATA AND DATA-DRIVEN DECISION MAKING- Mr. Hiroshi Tahata, JDU Head, Fujitsu

For decades, scientists have used data to develop a deeper understanding of their environment and to make predictions based on these discoveries. Today, data is the most asset for organisations, which has led to the creation of a wide range of novel data processing, transformation, analysis, and storage technologies.  However, there is still a degree of uncertainty surrounding big data, data science, and data-driven decision making.

For the uninitiated, big data refers to any massive and complex collection of data, whereas data science is the discipline that leverages this data to provide useful insights. Data-driven decision-making is an approach to problem-solving in which a well-defined set of activities is guided by decisions that are drawn from insights extracted from big data analysis.

What is data science?

As the world’s reliance on technology grows, it is evident that data is a valuable commodity. Businesses and organisations have resorted to data science to make sense out of this data, and it is now employed in a wide range of industries, including retail, healthcare, and finance, with its popularity only expanding. However, data science involves more than just gathering and crunching numbers; it also includes a thorough understanding of the business environment in which the data was gathered.

This process typically begins with data gathering, then moves on to data interpretation, and lastly, a conclusion is derived from it. Insights are produced from data using a variety of approaches, such as statistics, machine learning, and artificial intelligence. This enables data scientists to identify any confounding factors and draw valid conclusions. As the world relies increasingly on data to make well-informed business decisions, it is evident that data science is here to stay.

However, the introduction of big data in recent years has transformed the area of data science many notches higher, yielding new opportunities for analysis and prediction. Big data has revolutionised how businesses operate, and it will continue to do so as long as we have the means to interpret it usefully. With new solutions that address the entire data management ecosystem, big data technologies make it technically and economically feasible not only to gather and store larger datasets, but also to analyse them to unearth new and important insights. Usually, processing big data entails a common data flow – from the gathering of raw data to the consumption of actionable information. As more and more devices become interconnected, there will be an increase in the amount of big data that must be processed.

How is data-driven decision making connected to big data? 

In today’s competitive marketplace, data-driven decision-making has become critical for success, and data science is the key to uncovering the insights hidden in big data. A data study involves the large-scale analysis of data to develop a knowledge of phenomena. This is known as a DDD metric that assesses data that can be used by businesses to make enterprise-wide decisions. Essentially, data-driven decision-making is the process of making crucial business decisions based on data analysis. This data can be analysed in-house or by contracting an external team.

Most business system data is collected by computers, which are then used to generate DDD automatically. For instance, Wall Street traders use automated systems to purchase and sell shares based on certain parameters. It is impossible to manually track the rapid changes in share markets and the swift movements of exchanges and make instantaneous decisions. Computers, therefore, make these unlikely rapid trade selections based on data predictions. To increase the efficiency of these computers, data scientists are always attempting to improve them.
