Big Data has become an integral part of the IT Industry, thanks to the actionable insights and results that can be retrieved. Big Data is the collection of data from traditional and digital sources. For example, it includes everything we do online, from making a search via a search engine to sending an email.

The amount of data in the world is continuing to grow at an exponential rate. Therefore, to better understand Big Data, the fields of Data Science and Analytics is becoming increasingly important. However, it can be difficult to distinguish between the terms Data Science and Data Analytics. Despite the two being interconnected and both working with Big Data, they provide different results and pursue different approaches.

What is Data Science?

Data Science is a multidisciplinary field focused on extracting information from large sets of structured and unstructured data.

Data Scientists use several different tools, including Computer Science, Statistics and Machine Learning to look through extensive datasets to try and find new patterns and insights.

Data Science is commonly used in internet searches and digital advertising.

What is Data Analytics?

Data Analytics is similar to Data Science but is generally more focused. A Data Analyst will use raw data to answer questions, often producing results that will lead to immediate improvements.

Data Analysts focus on processing and performing statistical analysis on existing datasets. They will analyse the data, identify trends and turn it into insights that can be easily understood by technical and non-technical stakeholders, often presenting the data in a visual way.

Data Analytics is most commonly used in the healthcare, gaming and travel industry.

To summarise, Data Science generates questions to ask from any new insights or patterns found and Data Analysis attempts to answer these questions using hypotheses.
