What is the difference between a data scientist, a Big Data Professional, and a data analyst?

 

The world we live in is data-driven. In fact, the amount of digital data available is rapidly increasing, and transforming how we live. After Hadoop and other frameworks solved the storage challenge, the focus on data has switched to processing this massive volume of data. When it comes to data processing, the terms Data Science, Big Data, and Data Analytics come to mind, and there has always been a misunderstanding between them.
When it comes to data processing, the terms Data Science, Big Data, and Data Analytics come to mind, and there has always been confusion between them.
Let’s begin by understanding the terms Data Science vs Big Data vs Data Analytics:

Data science VS BigData VS Data Analytics

Data Science is a collection of tools, algorithms, and machine learning techniques aimed at uncovering hidden patterns in raw data.
It also entails solving an issue in a variety of approaches to arrive at a solution, as well as designing and constructing new data modeling and production processes using a variety of prototypes, algorithms, predictive models, and bespoke analysis.
Big Data refers to vast amounts of data coming in from a variety of sources and in numerous formats. It is a tool that may be used to examine data in order to make better decisions and strategic business movements.
The science of analyzing raw data in order to develop conclusions about it is known as data analytics. It ultimately comes down to extracting valuable information from data to aid decision-making. This procedure comprises data inspection, cleansing, transformation, and modeling.

What Does Data Scientist, Big Data Professional, and Data Analyst Do?

In this section, I will be covering the following topics in order to make you understand the similarities and differences between them.


Data Scientists: 

Data scientists collaborate closely with business stakeholders to understand their objectives and discover how data may help them achieve them. Cleaning and organizing data, gathering datasets, mining data for models, refining algorithms, integrating and storing data, and building training sets are all their responsibilities.

Skills needed to become a Data Scientist

88 percent have a master's degree, while 46 percent have a doctorate.
Knowledge of SAS or R in depth. R is frequently used in data science.
Python coding: Python, along with Java, Perl, and C/C++, is the most widely used coding language in data research.
Hadoop Platform: While it is not always required, having knowledge of the Hadoop platform is always advantageous in the profession. It's also a plus if you've worked with Hive or Pig before.
Database/SQL coding: While NoSQL and Hadoop have become major parts of data science, the ability to construct and perform complicated SQL queries is still preferred.
Working with unstructured data: A data scientist must be able to work with unstructured data, whether it's social networks, video feeds, or audio.



Big Data professionals: 

Big Data professionals are now more commonly referred to as analytics experts, as they investigate, analyze, and report on the huge volumes of data that the company stores and maintains. These experts discover Big Data difficulties and develop solutions, as well as employ fundamental statistical approaches to increase data quality for reporting and analysis, as well as access, change, and manipulate data.

Skills required to become a Big Data specialist

Analytical skills are necessary for deciphering data and evaluating what data is significant while preparing reports and solving problems.
Creativity: You must be able to come up with novel ways to collect, evaluate, and analyze data.
Mathematical and statistical skills: whether in data science, data analysis, or mega data, good old-fashioned "number crunching" is also required.
Computing: The backbone of any data strategy is computers. Programmers will be required to develop methods to convert data into information on a regular basis.
Business skills: Big Data experts will need to be aware of the company's goals as well as the underlying procedures that produce revenue and profits.

Data analysts: 

Data analysts collect, cleanse, and analyze data sets in order to turn them into actionable resources that may be used to solve problems or achieve organizational goals.

Skills required to become a data analyst

Skills in programming: Any data analyst must be familiar with computer languages such as R and Python.
Data scientists must have statistical and mathematical skills, including descriptive and inferential statistics, as well as experimental designs.
Skills in machine learning
Skills in data management include the capacity to map raw data and transform it into a format that allows for easier data consumption.
Skills in communication and data visualization
Data Insight: A professional's ability to think like a data analyst is critical.



Data scientists use exploratory analysis to uncover new information from the data. They also employ a variety of powerful machine learning techniques to predict the presence of a future event. This entails locating hidden patterns, unknown correlations, market trends, and other pertinent business data.
Big data professionals are responsible for dealing with large amounts of heterogeneous data obtained from multiple sources and arriving at a rapid rate.
Based on requirements, big data specialists explain the structure and behavior of a big data solution, as well as how it may be provided utilizing big data technologies such as Hadoop, Spark, and Kafka.
A data analyst's role is to take that information and use it to assist businesses in making better decisions.

Data Scientist vs. Data Analyst  Responsibilities

 A data scientist's main responsibilities include data transformation and purification. The data must also be pre-processed by a Data Scientist.
Machine learning is being used to forecast and classify patterns.
Optimising and tweaking predictive models.
Analyzing the company's requirements and developing questions to help solve them.
Creating dynamic infographics for team communication results.
A data analyst's main responsibilities include data analysis and interpretation utilizing statistical techniques.
Data extraction and storage in databases
Cleaning and filtration of data.
Exploratory data analysis is being used to visualize data.
Collaboration with teams to analyze business needs.

If it appears that the three occupations have a lot in common, it's because they do! Each business has its own set of policies and processes. In some firms, the data scientist may wear multiple hats.
