Before deciding whether to pursue data science or big data as a career, make sure you know how they differ.
Big data is the mass of structured, unstructured and semi-structured information that data professionals use to analyse insights leading to better organisational decisions and strategic outcomes. Data science is the broader field that comprises tools, data cleansing, analysis, algorithms and machine-learning principles to uncover patterns within raw data.
Big data features prominently in data science. If you’re a current or aspiring big data professional, consider a data science qualification to broaden your horizons.
What is the role of big data in business?
Big data has revolutionised business practices by:
- Enabling companies to fully understand the needs of their customers by analysing social media data, browser logs and text data mining.
- Reducing costs with predictive analytics to reduce guesswork. Businesses can predict inventory requirements and plan their production.
- Improving cyber security to detect cyber attacks in combination with machine learning and artificial intelligence tools and techniques. This provides a great opportunity within the cyber security space for those with big data skills, as Australia currently has a cyber security skills shortage.
Is big data necessary for a career in data science and machine learning?
Big data is grouped under data science, which is the umbrella term. It is fundamental to data science and machine learning. In everyday work, a data scientist encounters big data and needs to know how to use it.
Machine learning, a branch of artificial intelligence (AI), automates analytical model building. By learning from big data, it identifies patterns and makes decisions with minimal human intervention.
Even without prior experience, you can learn the necessary big data skills and analytical processes in as little as 12 weeks full time or 24 weeks part time with our Data Science & AI Program.
Are data scientists or big data professionals in demand?
In recent years, some of the world’s largest companies owe their successes to big data and the tools data scientists use for analysis. This development has generated a booming demand for data professionals, with almost every industry employing those with the relevant skills to enhance their business practices. Market leaders continue to look for skilled data professionals in Australia to ensure they keep their positions in a competitive market, meaning now might be the perfect time to upskill.
If you’re a big data professional, it’s a great time to become qualified in data science, expand your resume and become a more dynamic, future-focused employee. Businesses are looking for data professionals with practical skills in big data and also with training in data science, machine learning and artificial intelligence.

6 ways upskilling to data science can boost your career prospects
- You will become a more dynamic and valuable employee. In Australia, the demand for skilled data scientists outweighs supply. Companies are willing to reward skilled data scientists because they are seen as a valuable asset.
- You can help to optimise your business’s operations. Data scientists use data to increase business efficiencies to reduce costs and save money. For example, transport companies use route optimisation for quick, cost-effective deliveries.
- You can identify fraud and assess risk. By upskilling to data science, you can help your company’s cybersecurity by aiding in fraud detection and potential cyber-attacks.
- You can target markets. Data science and analytics enable a company to target ads at consumers personally to increase sales.
- You can deploy predictive analysis. Data science plays a pivotal role in predictive analysis to plan and manage costs. You can predict accurately how much a consumer will pay for a product and forecast when production will need to increase.
- You can make more money. By upskilling to data science from big data, your salary could almost double.
Given the benefits, it’s clear to see why upskilling to data science makes so much sense. Although big data professionals are in demand, employees educated and trained in data science are even more sought after, as their skills are viewed as wide-ranging across the breadth of a company.
