The coined phrase big data refers to the immense amount of data collected, stored and analyzed from every imaginable device and business in our modern culture, that are so complex and large that advanced methods of storage and extraction are needed. Traditional relational databases are typically unable to process big data. The threshold of database size before it’s considered big data is relative to each organization and tends to be a moving target, but could start with only a few terabytes, and for other organizations it might start at a petabyte. Generally speaking however, when data storage and data processing in particular become a challenge; big data management solutions are needed. The big data industry has grown at a staggering rate in recent years, with major providers such as Teradata, SAP, Oracle, and Dell EMC providing enterprise solutions, just to name a few. Database size is not the only consideration when big data solutions are needed, but perhaps the simplest to understand. Complexity, velocity (or speed), consistency, and the quality of data all become considerations at some point. Many enterprise big data solutions involve something that’s called parallel processing, such as the case with the popular architecture of MapR, which uses parallel nodes. With the MapR platform, database queries are divided across parallel nodes and then delivered through algorithmic reduction. It’s this framework that inspired and was adopted by Apache Hadoop, which is an open source project. Big data has become big industry, and many believe we are just at the dawn of this era of incredible growth.

Applications in Business and Industry

Big data is widely used in business and industry across various sectors, playing a crucial role in today's data-driven world. It refers to the vast volume, velocity, and variety of data that organizations collect from multiple sources. In business, big data is utilized in several key areas.

  • Firstly, big data analytics is employed to support decision-making processes. By analyzing large datasets, organizations can extract valuable insights that enable informed strategic planning and decision-making. This includes understanding customer behavior, market trends, and operational inefficiencies. Big data also helps businesses gain a deeper understanding of their customers. By analyzing customer data, organizations can personalize marketing efforts, create targeted advertising campaigns, and enhance customer experiences.
  • Furthermore, big data analytics aids in optimizing operational efficiency. By identifying bottlenecks and inefficiencies through data analysis, businesses can streamline operations, improve supply chain management, and increase productivity. In terms of risk management, big data analytics plays a vital role. Organizations can assess credit risks, market risks, and operational risks by analyzing large datasets, leading to better risk mitigation strategies and decision-making.
  • Big data is also making a significant impact in healthcare and life sciences. By analyzing patient data, genomic data, and clinical trials, it enables personalized medicine, improved disease management, and advancements in healthcare research.
  • The use of big data extends to various other sectors. For instance, it helps in fraud detection and prevention, predictive analytics, smart city planning, marketing, and advertising optimization, and financial services analysis.

In summary, big data has become an invaluable asset for organizations across different sectors. Its utilization allows businesses to gain insights, improve decision-making, enhance operational efficiency, and drive innovation and growth. Now let’s take a look at some considerations for big data jobs and how this might impact employment opportunities.

Education and Training

Education and training play a pivotal role in preparing individuals for careers in big data. As the world becomes increasingly data-driven, organizations need skilled professionals who can harness the power of vast amounts of information. A solid educational foundation provides a comprehensive understanding of data analysis techniques, statistical modeling, machine learning, and programming languages crucial for working with big data sets. Ongoing training keeps professionals up to date with evolving technologies and methodologies, enabling them to adapt to changing industry trends. Proficiency in data analysis and interpretation ensures accurate decision-making, improved business strategies, and innovative problem-solving. Education and training are therefore essential for individuals aspiring to succeed in the dynamic field of big data.

The Future

Where is the field of big data headed, and how will it impact our lives? Big data will continue to impact all industries in profound ways, from healthcare, government, education, retail, manufacturing, advertising, science and finance just to name a few. Every touchpoint of our digital lives will continue to collect data and provide opportunity for insight and decision making. While the notion of big data itself can be deemed somewhat of a concept, it has created very tangible possibilities and opportunities. In fact, some of the major technological breakthroughs in big data have even spawned new big industries. One example of a newly created industry is what’s called the Internet-of-Things (IoT). Countless physical devices are connected to the internet and generating data on our usage, location, and behavior from mobile phones to TVs and even refrigerators. More and more device manufacturers are embedding internet connectivity in all devices. It’s this inter-connectivity between devices, and the subsequently vast amount of data collected, that the parent makers of them which will leverage to provide some kind of value. IoT has become one of the new frontiers and fastest growing sector for careers that is the direct result of big data evolution. More information on IoT jobs can be found here.
