We live in a world where data is king. Our lives, our personal information, our finances, our jobs, our entertainment, have all become digitized and stored as data. Paper and hardcopy are dead—long live the electronic revolution!
As a result of this increase in generated data, there is a corresponding need to study and maintain it. That’s where the field of data science comes in. Of course, you need the right tools to conduct all the tasks associated with data science.
Do you see where this is heading?
Today, we’re looking at data science, specifically the most popular tools used to make sense of data and what advantages each one offers. But first, a definition.
What is Data Science?
Data science is defined, unsurprisingly, as “the study of data.” That certainly narrows it down! Fortunately, there’s more to it. The purpose of data science is to gain knowledge and insights from all kinds of data, structured or unstructured.
The process includes creating and implementing ways of recording, analyzing, and storing data to glean useful information effectively. Data science isn’t computer science; the latter focuses on creating algorithms and programs for processing and recording data, while data science focuses on analysis and may not even require a computer!

Why Data Science?
We mentioned earlier that since so much of life is digitized data, it’s only logical to study data science. But there are specific reasons why understanding data science and applying it to more careers is a good idea:
- Fraud prevention. Data scientists can identify anomalous data and create methodologies for predicting fraudulent incidents
- Informed decisions. Accurate, useful data helps management make better decisions, ones that have an increased likelihood of success
- Better customer experiences. The more appropriate and relevant data that businesses have on their customers, the better they can tailor the experience for each consumer
