Choosing between these paths requires a clear understanding of how different functions contribute to an organisation.

In this article, we explore the specific differences between these two high-demand fields. We will examine the tools, salaries, and daily responsibilities that define these roles in a local context. 

We compare data science and data analytics in detail to help you find the best fit for your goals. Understanding these differences is crucial if you want to work in tech by 2026.

What Is Data Analytics?

Data analytics involves collecting, cleaning, and analysing raw data to derive useful insights. It helps companies make decisions based on facts rather than guesswork. Analysts use statistics and visual tools to show how a business is doing and where it can improve. This work is important for teams like marketing, finance, and operations that need to track results.

Key aspects of data analytics include:

• Collecting raw data from sources like websites, surveys, and IoT devices.
• Cleaning datasets to ensure accuracy before performing any statistical analysis.
• Using descriptive analytics to explain what happened in a specific business period.
• Applying diagnostic analytics to understand the reasons behind certain performance trends.
• Creating visual dashboards using tools like Tableau or Power BI for stakeholders.
• Managing structured data within relational databases using SQL queries.
• Supporting marketing and financial forecasting through detailed reporting.

What Is Data Science?

In South Africa, data science combines statistics, mathematics, and programming to turn complex data into actionable insights. This skill is in high demand for digital change in banking, retail, and healthcare. Data scientists do more than report on data; they build models and algorithms that help machines learn. They often work with unstructured data, such as text or images, to solve large-scale problems.

Key aspects of data science include:

• Banking and finance sectors use these skills for fraud detection and credit scoring.
• The government applies these techniques to improve service delivery and predict municipal needs.
• Professionals typically work in major tech hubs like Johannesburg, Cape Town, and Pretoria.
• The field focuses on local challenges, such as optimising water use or managing infrastructure.
• Programming languages like Python and R are the primary tools for building models.
• Machine learning engineers create automated systems that adapt to new information.
• Research-based education is regularly a prerequisite for advanced positions in this field.

What Do Data Analysts and Data Scientists Actually Do?

In South Africa, data analysts and scientists turn large volumes of raw information into actionable business insights for key sectors such as finance and telecommunications. While they share a common goal of data-driven growth, their daily tasks differ significantly in technical depth. Analysts assess data quality and produce reports on business results to inform current operations. In contrast, scientists design complex data systems and develop predictive software to forecast future market trends.

To understand how these roles function within a South African corporate structure, it is helpful to examine their workflows. 

The following sections detail the unique responsibilities associated with each career path.

1. What do data analysts actually do?

In South Africa, data analysts are like company historians. They turn numbers into clear stories for managers. They primarily work with structured data from company databases to improve operations and identify market trends. Their role is critical to documenting what happened and why, enabling businesses to adjust their plans quickly.

The following list highlights the core duties performed by data analysts in a typical business environment:

• Prepare raw data from various corporate sources for internal analysis.
• Create visual dashboards to present trends in consumer spending or marketing.
• Analyse key performance indicators to help retailers understand store performance.
• Write complex SQL queries to extract information from central databases.
• Collaborate with department heads to answer specific operational
