Unlocking the world of data!
Ever since the invention of computer, the term data was used to denote the information in a computer. Before the development of computing devices, people used to collect data and analyse it, and impose pattern to it manually. Today, in the world of technology, computers are widely used for collecting, and sorting data in many disciplines like marketing, social services and scientific research. These sorted data are used for improving processes, products, services and software.

Frequently Asked Questions
What is Data?
Data is a set of values that exist in different forms like numbers or text on a piece of paper, bits and bytes in electronic memory and facts in human memory. Data has a meaning only when it is placed in a context. The terms data and information are used interchangeably but it has a vast difference in its meaning. Data is a concrete concept and information is a more abstract concept. For example, the depth of Indian Ocean is a data, wherein, the etymology of Indian Ocean is an information.
Computers use different types of data stored in digital format like text, numbers, multimedia. Data Scientist and Business Analyst deals with these data. A Data Scientist uses scientific methods and algorithm to extract knowledge and insights from structured and unstructured data. A business analyst guides in improving businesses by analysing business model data and its integration with technology.

Relationship Between Data Scientist and Business Analyst
The terms Data Scientist, Data Engineer and Business Analyst are deeply intertwined with each other.
The data scientist is an analytical expert who utilizes his skills to gather and analyse large set of structured and unstructured data.
Data engineer is the one who is in charge of managing data workflows, pipelines and ETL processes and provide a reliable infrastructure for data.
Business analyst is the one who bridges the gap between IT and the business. They analyse an organization, determine requirement and deliver data driven recommendations.
In other words, the science of data that uses statistics, algorithms and technology is called as Data Science. And, the statistical study of the structured data is known as Business Analyst.
The Data Science Hierarchy of Needs
The Data Science Hierarchy of Needs is a framework which helps in understanding the career role to choose from Data Scientist to Business Analyst. This is the key guide that connects your current skills and where you want to go with your career in future.
At the bottom of the pyramid is data collection. What data is available, what data do we need, what data is coming through and how? These questions are analysed and collected at this stage. A data driven organization starts with basic data collection like logging errors, recording transactions and digitizing analogue data.
Next stage analyses on how the data flow through the system. It also analyses where you store it and how easy it is to access and analyse those data. This stage starts with basic data-organization like transforming, cleaning and storing data. A matured company may build a data ETL pipeline, data warehouse or a data lake at this stage.
Exploring, transforming and data cleaning happens in the next stage. This stage helps you to identify the missing data, misinterpretations and unreliable data. It starts with basic data analysing tools like reports and dashboards to explain what is happening and why is it happening in the organization. Matured companies incorporate data mining, diagnostic analytics and descriptive analytics at this stage.
The most interesting data stories are found in this stage. It defines the matrix to track, do user segmentation and start to predict or learn training data by generating labels. This stage will help you to predict what will happen in the future. Companies may incorporate predictive analytics and prescriptive analytics and machine learning at this stage in their data science pipeline.
Deep learning stage where you deploy a simple ML algorithm and think of new features and signals that might affect your results.
The final stage where you are ready to go ahead and explore your instrumented, organised and cleaned data. Your data are ready for AI. Data science loop is closed, and humans are removed from the process at this stage.
How this pyramid affects the career of individual data scientist?
Every company and every sector are different. Firms decide on advance research or machine learning based on the business they are in. Like research, companies differ in their staffing strategies as well.
Though many companies prefer generalist to own the large portion of the project, matured companies prefer specialist for each layer of the pyramid. The specialist model gets better results at each stage. This model requires huge communication overhead as each portion is covered by different people. Generalist model helps people to build data science products quicker. However, it is a challenge to have someone with such diverse background.
Difference Between Data Scientist and Business Analyst
From the above pyramid it is clear that both Business Analyst and Data Science involves data gathering, modelling and insight gathering, yet both are different. Below is a detailed comparison between data Science and Business Analytics.
The term Data Science was coined by DJ Patil and Jeff Hammerbacher in 2008. The term Business Analytics has been used since the late 19th century and the term was introduced by Frederick Winslow Taylor.
Data Science study about data using statistics, technology and algorithm. Wherein, Business Analytics is the study of business data.
When Data Science use both structured and unstructured data, Business Analytics use mostly structured data.
A Data Scientist should be an expert in skills like computer science fundamentals, programming, and linear algebra. As the main role of a Business Analyst is to analyse the trends in business, the skills required are business simulations and business planning.
Data Science involves lot of coding but Business Analytics does not have much coding involved. It is mostly statistics oriented.
The common tools used by Data Scientist are R, Python, scikit-learn, and PyTorch. Business analyst use tools like Excel, Tableau, SQL and Python.
Data Science results give insights but can’t be used for daily business decision. Business Analytics results are key decision makers.
The future trend of Data Science is Machine Learning and Artificial Intelligence. Wherein the future application of Business Analytics would be in Cognitive Analytics and Tax Analytics.
Industry Requirement of Data Science
Data helps us achieve major goals which required a great deal of time and energy just a few years ago. Data Science is used in different fields for automation, classification, forecasting, recognition and recommendations. Below are few areas in which data science is used to innovate and create new products.
Data Science is used in almost every industry. But it is most important in cybersecurity. Data Scientists identify potential cybersecurity threats with the help of machine learning and predict the risk based on past behaviour patterns.
Medical practitioners are finding new ways to understand diseases, diagnose faster and develop preventive medicines and explore new treatment options.
Data Science is used in logistics industry both internally along its delivery routes. They create optimal routes for drivers based on weather, traffic, construction, etc.
Entertainment apps and software like Netflix, Spotify and Instagram use data for finding out what their viewers might like and suggest them what to watch or listen next.
e-Commerce giants like Amazon use data for improving customers shopping experience. They use collected data for determining customer behaviour and shopping pattern and suggests personalized product recommendation.
