According to the Oracle Corporation (the guys that developed Java, the programming language):

“Data science combines multiple fields, including statistics, scientific methods, artificial intelligence (AI), and data analysis, to extract value from data. Those who practice data science are called data scientists, and they combine a range of skills to analyze data collected from the web, smartphones, customers, sensors, and other sources to derive actionable insights.”

What a mouthful. 

In layman’s language, data science involves using tools to analyze data and uncover what the data means. For instance, if I was a data scientist at an eCommerce company, I would analyze data from the CRM tool at my disposal to better understand what the customer needs.

But don’t get me wrong, data science encompasses many fields. What I mean is: data science isn’t all about analyzing data to make sense of the stats and whatnot. Data science goes way beyond that. If you’re new, there are many specializations of data science, such as:

Data Mining –

Just like the term suggests, data mining a subset of data wrangling involves collecting raw data and turning it into meaningful information. Without mining, you have no data with which to work.

Data Architecture –

Mining data is not enough. You must develop the architecture (including physical assets, policies, rules, standards, and models) “…that govern the collection, storage, arrangement, integration, and use of data…” in your business.

Data Engineering and Data Warehousing –

Data engineering involves preparing data for analytical or operational use. Data engineers generally ensure data is flowing within an organization. Data warehousing is all about storing data in a secure, reliable, and easy-to-manage manner.

Data Visualization –

Raw data (numbers, stats, demographics, etc.) don’t make sense to the board of directors and other stakeholders. Data visualization is the graphical representation of data. It involves using charts, graphs, maps, etc. to make sense of raw data.

Artificial Intelligence (AI) and Machine Learning –

According to Britannica.com, AI is the ability of a computer to perform tasks associated with intelligent beings like animals and humans. And according to IBM, machine learning is a branch of artificial intelligence, which focuses on the use of computer programming to imitate the way human beings learn.

Data Analytics –

Data analytics is the science of analyzing data to make conclusions about that data, according to Investopedia.

Business Intelligence and Strategy –

Business intelligence involves using technology-driven processes to analyze data to derive information that organizations can use to make informed decisions.

As you can see, there are many fields in data science. You can venture into any of the above fields depending on your skills and personal preference. But which skills do you need to get started in data science? Read on to learn more.
