Difference between Data Science vs Data Analytics
Data science is the study of where information comes from, what it represents and how it can be turned into a valuable resource. Data science is all about uncovering findings data through a different process, tools, and techniques involved to identify patterns from raw data. These raw data are basically Big Data in the form of structured, semi-structured and unstructured data. Data Analytics, or data analysis, is similar to data science, but in a more concentrated way. The purpose of data analytics is to generate insights from data by connecting patterns and trends with organizational goals. Data Analytics uses basic query expressions like SQL to slice and dice data.
Data Science
“Data Science is when you are dealing with Big Data, large amounts of data”.
- Data Science is mining large amounts of structured and unstructured data to identify patterns.
- Data Science includes a combination of programming, statistical skills, Machine Learning algorithms.
- Data Science is the art and science of extracting actionable insight from raw data. We can define data science as a multidisciplinary blend of data inference, algorithm development, and technology in order to solve analytically complex problems.
- Mining large amounts of structured and unstructured data to identify patterns can help an organization rein in costs, increase efficiencies, recognize new market opportunities and increase the organization’s competitive advantage.
- Data scientist work depends on a requirement, business needs, market requirement and exploring more business from black data.
Data Analytics
- Data analytics deals less in AI, machine learning, and predictive modeling, and more with viewing historical data in context.
- Data analysts are not commonly responsible for building statistical models or deploying machine learning tools.
- Comparing data assets against organizational hypotheses is a common use case of data analytics, and the practice tends to be focused on business and strategy.
- Data Analysts are less likely to be versed in big data settings.
- Data Analysts wrangle data that are either localized or smaller in footprint.
Data analysts have less freedom in scope and practice and practice a more focused approach to analyzing data. They’re also much less involved in the culture of data work.

Key Differences Between Data Science and Data Analytics
Both are popular choices in the market; let us discuss some of the major Differences Between Data Science vs Data Analytics:
Data generated from different sources like financial logs, text files, multimedia forms, sensors, and instruments are Big Data. Simple Business Intelligence tools are not capable of processing this huge volume and variety of data. This is why we need more complex and advanced analytical tools and algorithms for processing, analyzing and drawing meaningful insights out of it.

- Data scientists essentially look at broad sets of data where a connection may or may not be easily made while Data Analytics looks at a certain set of data to communicate further.
- The data science field employs mathematics, statistics, and computer science disciplines, and incorporates techniques like machine learning, cluster analysis, data mining, and visualization while Data Analytics works on structure query language like SQL/ Hive to drive final output.
- The job role of a data scientist strong business acumen and data visualization skills to converts the insight into a business story whereas a data analyst is not expected to possess business acumen and advanced data visualization skills.
- Data scientist explores and examines data from multiple disconnected sources whereas a data analyst usually looks at data from a single source like the CRM system or a database
- A data analyst will solve the questions given by the business while a data scientist will formulate questions whose solutions are likely to benefit the business

Conclusion
The seemingly nuanced differences between data science vs data analytics can actually have a big impact on a company. Data Science is a new interesting software technology, which is used to apply critical analysis, provide the ability to develop sophisticated models, for massive data sets and drive the business insights. Data science is an umbrella term used to describe how the scientific method can be applied to data in a business setting. Data science is also playing a growing and very important role in the development of artificial intelligence and machine learning. Although the differences exist, both are important parts of the future of work and data. Data Analysts take direction from data scientists, as the former attempts to answer questions posed by the organization as a whole. Both data science vs data analytics should be embraced by companies that want to lead the way to technological change and successfully be understanding the data that makes their organizations run. A company needs both data science vs data analytics in their project. Both data science vs data analytics are part of the company’s growth.
