You may have often heard the comparison that in this age of technology ‘data is like gold’. According to a report by EMC2, the digital universe is growing at a 40% rate per year in the next 10 years. Companies have been extensively using data science, big data, and data analytics, supported by robust technological solutions and highly trained teams. As Oracle suggests companies have a treasure trove of untapped data.  Along with the growth of data, there is a rise in the number of roles and opportunities concerned with harnessing this data. Data Science, Big Data, and Data Analytics — we have all heard these terms. Apart from the word data, they all pertain to different concepts. This article will help you understand the concepts of Data Science vs Data Analytics vs Big Data and also guide you on the various ways you can become a professional in any of these fields.

Data Science vs Data Analytics vs Big Data: What are the Differences?

Unless we are experienced in those professional fields, it is quite confusing. This makes it difficult for anyone who is looking to start a career in data-related work. This is why we have decided to throw light upon the characteristics of the three profiles.

Data Science

When the term ‘science’ is associated with data, one can understand that it is a broad area where scientific methods, maths, statistics, and a host of other tools are applied to data sets in order to extract the required knowledge and insights. Data science is an umbrella term for all data conversion tools, methods, and scientific models to understand underlying patterns of complex systems.

Data in raw form is unintelligible and obscure, with unfiltered noise, and misleading patterns and information. This is where data scientists play an important role; deriving meaningful conclusions from collected data. Some time ago, Harvard Business Review declared ‘data scientist’ as the “sexiest job of the 21st century” and judging from how important data is nowadays, it is no surprise.

Applications of Data Science

There are a lot of areas where data science has disrupted the industry and has changed the way things worked. Here are some of the prominent areas where data science plays huge roles:

With the help of data science, the patterns or the behaviors of the user can be determined and can be targeted accordingly. This has led to digital ads becoming more successful, having higher CTRs than traditional print advertising.

2. Search Engines

Data science is behind the success of the algorithms used by search engines. To deliver the best results for a search query, these search engines take the help of data science to process the huge amount of queries and transform them into meaningful patterns. This provides the best results and also helps the search engine to keep on developing its understanding of the users’ requirements.

3. Delivery Logistics

Nowadays, e-commerce has become a prominent industry with a lot of people shopping online. This has led logistics companies to improve their delivery experience; leading companies to use data science to understand the best routes, transportation modes, and delivery times. Thus, data science has helped these companies to deliver better with cost-efficiency.

4. Fraud and Risk

Finance companies have to be constantly on their toes to not fall into bad loans, debts, or losses. With the help of data science, the companies can do a wider security check. They can also improve the profiling of customers and also analyze previous data to find patterns that would help them in fraud and risk detection.

Big Data

To define in a simple way, big data is the large volume of data (both structured and unstructured) that cannot be analyzed using traditional methods. The term, “big data,” is itself a relatively new one and its importance has grown in the last 5-10 years, with organizations beginning to see the various advantages that it offers.

Though data has always been there and the collection of data is also nothing new, the concept of big data is totally different. Big data can be defined by three Vs – volume, velocity, and variety. As already mentioned, big data is literally huge, and other than that, it also streams at an unprecedented speed and comes from a variety of sources.

The ability to handle this data and analyze the meaningful patterns is going to help companies to reduce their production time, offer personalized services, reduce waste and make a quick decisions regarding customer buying habits.

Applications of Big Data – Industries and Areas

Big data is relatively new compared to the traditional method of using analytics in businesses and has already found applications in various industries. Here are some examples of applications of big data:

Big data can be used to analyze the popularity of courses and e-learning companies can give more attention to the courses on a regular basis.

2. Finance Industry

Banks suffer huge losses through events like fraud and bad loans. Through big data, companies can check for such risk patterns and keep track of any such transactions or anticipate if a customer is going to default in repaying the loans. Big data can also help companies to understand the spending behavior of high-worth customers and offer them services that will beneficial to both sides.

3. Internet

Big data is going to help online marketing divisions to better understand their customers or clients.
