What are data science and data analytics

Data science combines various scientific methods, algorithms, and systems to extract meaningful and actionable insights from data. This data can be either structured (organized in a certain way) or unstructured (like random texts or images). 

Think of data scientists as the detectives of the digital world. They stand at the intersection of machine learning (a type of artificial intelligence that lets computers “learn” from data), artificial intelligence (computers mimicking human intelligence), and deep learning (a subset of machine learning inspired by the structure of the human brain).

These professionals sift through enormous amounts of data, uncover hidden patterns, make predictions about future trends, and devise solutions to complex problems. Their work is essential in converting raw data into valuable information that aids in making informed business decisions.

Now, let’s consider data analytics. While it’s closely related to data science, data analytics is more specific. It deals with examining, cleaning, and transforming data to extract valuable information, identify patterns, and support decision-making.

Data analysts use tools like Tableau and Power BI to visualize data. By creating graphs, charts, and other visual aids, they transform intricate data into understandable and engaging stories. These visualizations can play a key role in shaping business strategies and guiding important decisions.

The skills and tools of the data trade

Every good data scientist has solid math abilities, statistical skills, and computer science knowledge, as well as data analysis and programming skills. These skill sets can earn them a variety of roles, and have responsibilities such as data engineering, predictive analytics, problem-solving, and data wrangling.

These intricate tasks call for proficiency in programming languages and tools like Python, SQL, Spark, and Hadoop.

Conversely, data analyst roles combine business analytics and business intelligence. They excel in interpreting data, identifying trends, and leveraging historical data to forecast future patterns. Their toolkit often includes Excel, Power BI, SAS, and Tableau. Beyond just analyzing, these professionals use data dashboards and data modeling, converting raw data into visual narratives to shape business decision-making.

A job role comparison

Let’s discuss data scientists’ and data analysts’ distinct contributions to their fields. 

Data scientists are the architects behind complex data modeling and algorithm development. They dive deep into large datasets to uncover hidden patterns and insights. Their expertise in machine learning and artificial intelligence allows them to predict future trends and behaviors. 

For instance, a retail company that needs to predict future sales trends and customer preferences might hire a data scientist. Their role would mainly be developing predictive models that analyze past sales data, customer reviews, and market trends to keep the company ahead of its competitors.

On the other hand, data analysts are more like meticulous data inspectors. They make sure data is accurate and relevant, and then they interpret it for their stakeholders (like business executives or investors, for instance). They might also use visualization tools to transform raw data into clear, actionable insights. 

Consider a healthcare provider wanting to improve patient satisfaction. They might hire a data analyst to sift through patient feedback, identify common concerns, and present findings in a digestible format. This would make it easy for the organization to make informed changes to its services.

Additionally, in the realm of finance, banks often employ data analysts to interpret transactional data, detect suspicious activities, and offer personalized financial advice to their customers based on spending habits and account history. Data scientists’ and data analysts’ career paths can also vary in pay, and perhaps accordingly, in complexity.


The average pay for a data scientist in Switzerland is CHF 116,437 per year, while a data analyst in the same area averages CHF 95,739 per year.

While data scientists typically command higher salaries than data analysts, this compensation landscape can shift based on variables such as experience, specific geographic location, and educational qualifications.

Plus, as the demand for these roles increases, so does their potential for salary growth.


Although the two fields are closely related, data science and data analytics have different levels of complexity. Their depth and approach to data also vary significantly.

Data science is often seen as the more intricate discipline, delving into deeper layers of data, employing advanced algorithms, and predictive modeling to uncover hidden patterns and insights. It requires a broader skill set, encompassing everything from machine learning to data engineering. 

Conversely, data analytics is more focused and straightforward, primarily centered on processing, interpreting, and visualizing data to draw immediate insights. 

While data analysts work with structured datasets to answer specific questions, data scientists navigate both structured and unstructured data, often venturing into uncharted territories to discover new knowledge or create predictive models. 

Using data science and data analytics in business
