Data Science vs. Big Data vs. Data Analytics – Know the Difference

Data is rapidly growing along with the speed of technology advancements. More data has been created in the recent few years than in the entire previous history of the human race.

Do you know that an approximate of 1.7 MB of new information will be generated every second by the year 2020????

Remember, big data is not a fad but is a revolution which has begun and with no doubt, it will soon touch upon each business. Along with the data volume, our ability to analyze it efficiently to derive useful business insights is also growing, and in the next five years, we can expect even in startups there will be some form of data analytics working and kindling the business growth.

The professionals embarking on a career change, often get confused and unsure of the difference prevailing in Data Analytics, Big Data Analytics, and Data Science.

Do not worry, we have our ear to the ground and that is why we decided to come up with an article that clearly explains the difference between all these buzzwords and also the career associated with them.

Data Science Vs Big Data Vs Data Analytics-Difference

Data Science Vs Big Data Analytics Vs Data Analytics

Let’s first see what does each term precisely means and then we see their applications.

Data Science Vs Big Data Vs Data Analytics

What is Data Science?

Data Science is an interdisciplinary field embracing all that is associated with structured and unstructured data, starting with preparing, cleansing, analyzing and deriving useful insights. It is a combination of mathematics, statistics, intelligent data capture, programming, problem-solving, data scrubbing, different perspectives of looking at things, preparation and data alignment.

In a nutshell, it is the combination of several techniques and process working on data to gain knowledgeable business insights. By using scientific methods, algorithms, processes, and systems to effectively extract information that can be used by business to make crucial business decisions.

What is Big Data?

If we say, Big Data, we are not talking about data stored on one computer, instead, the humungous volumes of non-aggregated raw data stored in different places with its size varying up to petabytes. With more and more data getting generated every millisecond from various sources, data doesn’t come in standard form but has been produced in varieties of form. In fact, 80% of the data generated today are unstructured, and it is highly impossible to handle them efficiently only by using traditional technologies.

In earlier days, the amount of data generated was not high and we kept archiving them, and was performing an only historical analysis. However, one important thing to keep in mind is that “Big Data is something that is very important be to analyzed for so that we can derive at useful insights to make better and strategic business moves.”

The World’s leading global research and advisory company, Gartner is defining Big Data as “High-volume, and high-velocity and/ or high variety information assets that need forms of information processing that are cost-effective and innovative and can allow enhanced decision making, insight and process automation.”

What is Data Analytics?

Data Analytics is the process that involves an application of algorithmic or mechanical procedures to derive at useful business insights. The techniques and technologies of Data analytics are widely used in industries to make informed decisions to verify or disapprove the current models and theories.

Applications of Data Analytics:

1) Energy management: Most of the companies use Data analytics for energy management which includes smart-grid energy, building automation in utility companies, energy optimization, and energy distribution. The primary focus is on managing the service outages, monitoring and controlling of network devices and dispatch crews. Integrating millions of data points within the network performance of Utilities lets the engineers monitor their networks by utilizing analytics.

2) Healthcare: Cost pressures are the major challenge faced by hospitals and that is what restricting them from treating many patients effectively. Machine and instrument data proves to be beneficial in tracking and optimizing the treatment as well as the patient flow and use of equipment can be tracked. This helps in improved quality of care and a predicted gain of 1% efficiency yielding a savings of over $63 billion in healthcare worldwide.

3) Gaming: Collecting data to optimize and spend within across games is the primary advantage of data analytics in Gaming. Those companies into manufacturing of games gain better insights of user likes, disliked and the relationships.

4) Travel: We can optimize the buying experience via weblog analysis, mobile data analysis and social media using Data Analytics. What customer prefers and desires can be extracted. Tailored offers and packages can be promoted in accordance with the subsequent browsing of the customer that would help the company to achieve better conversions.
