Before discussing the future of data science and big data analytics, let’s consider a scenario. Imagine you’re the head chef at a reputed restaurant that sources ingredients from all over the world. Say, you’ve got baskets full of apricots from Turkey, Kiwi from New Zealand, almonds from California, and bananas from Brazil. Your job will be to decide how to prepare dishes that combine these different varieties the best. From finding out the nutritional value of these fruits to which flavors work well together and what additional ingredients should be added to make the unified dishes more delicious, you’ll have to derive value from these fruits. At the same time, you’ll need to consider how these dishes would influence the restaurant’s menu and reputation.
This analogy would help you to understand how big data and data science work. Just like the different fruits, big data is a large volume of data sets – both structured and unstructured. Thus, big data refers to an immense volume and variety of information assets that are generated rapidly. Similar to the chef’s expertise, data science helps you to process such data to get useful insights for informed decision-making and process automation. The future of both these domains is bright though data science has a clear edge. Perhaps that’s why “how can I become a data scientist?” is a frequently asked question and reputed data science bootcamps in Silicon Valley attract participants galore. If you too have a plan to become a data scientist or work with big data, knowing what the future holds for them would help.
In today’s digital landscape, data has become one of the biggest and most important assets for almost all organizations. Data can be fetched from anywhere and it’s actually transforming the way we live.
If you’re interested in working with data, it’s extremely important to have a clear understanding of the different avenues related to it. In this post, we’ll discuss the differences between data science and big data analytics. Though these terms are interlinked, there’s a huge difference that lies between them almost in every aspect. Let’s start the discussion.
The promising future of big data and data science
From financial services and retailers to media and telecommunications, big data is increasingly used for operational functions, compliance and customer analytics, and fraud prevention. According to IDC, by 2025, it’s expected that 75% of the global population or 6 billion users will be interacting with online data each day. This means in every 18 seconds, each of these connected users will be having one data interaction at the least. As businesses gain the capability to store such huge volumes of data, they’ll need to get them analyzed too to benefit from useful insights. And that’s where data science can help. For instance, if you’re sitting on a pile of data, you can use different types of sophisticated statistical and predictive analysis (think AI or machine learning) to make sense of the structured and unstructured data.
According to the US Bureau of Labor Statistics, 11.5 million jobs in the field of data science and analytics are expected to open up by 2026. With a dearth of data scientists at present, the gap would widen in the future if adequate experienced professionals aren’t trained. This makes data science bootcamps in Silicon Valley an attractive prospect to jumpstart your career in data science.
Data science
It’s the field that encompasses almost everything related to data – from preparation of data to data cleansing to data analysis, and deals with both structured and unstructured data. Data science can be considered as an umbrella term which includes various scientific methods within its ambit. It combines statistics, mathematics, problem-solving, and much more.
Big data analytics
This field involves the application of mechanical or algorithmic processes in order to derive operational insights for complex business solutions. It’s all about examining raw data to support decision making. Big data analytics involves inspecting, transforming, cleansing and modeling data.
